In today's design industries, the concept of generative design for product development is progressively evolving. When a product has been on the market for an extended period of time


INTRODUCTION
In product development, including product design improvements, it is emphasized that everything is considered at the initial design stage because it significantly affects the later stages of product development and throughout the product life cycle (Juniani et al., 2022).
The relationship between Fusion 360 simulation and optimization in product development is intertwined and complementary.Fusion 360 offers simulation and optimization tools that work together to improve the design and performance of products.Simulation in Fusion 360 involves creating virtual prototypes and subjecting them to various tests and analyses to evaluate their behavior under different conditions.This includes structural analysis, thermal analysis, fluid flow analysis, and more.Simulation helps identify potential design flaws, optimize performance, and ensure that the product meets desired specifications and requirements.
Structural analysis helps assess the performance and reliability of the redesigned product.It allows engineers to analyze how the product will behave under different loads, stresses, and environmental conditions (Rahman et al., 2020;Setiawan et al., 2023).By simulating and analyzing the structural integrity, engineers can identify weak points, potential failure modes, and optimize the design to ensure it meets safety and performance requirements.Structural analysis plays a crucial role in product redesign by providing valuable insights into the performance, reliability, and optimization of the redesigned product (Jumandono & Juniani, 2017;Prabowo et al., 2018).It helps engineers make informed decisions, optimize materials and designs, reduce costs, ensure compliance, and ultimately deliver high-quality products to the market.This article's writing structure is divided into four sections.The second section presents a literature review of research materials and describes the research methodology in depth.The third section presents the results and the discussion.The study's findings are then summarized in the final section.

MATERIALS AND METHOD
This section will discuss the primary literature review supporting this article, as well as the research methods.

Product Redesign
Existing products are frequently redesigned to create new products.Product redesign has become an evolutionary strategy in product development (Juniani et al, 2022;Zhang et al., 2019).The primary objective of product redesign is to increase customer contentment by enhancing selected target features.Consequently, identifying product features that will be improved is an essential aspect of product redesign research.These enhanced product features are implemented through product redesign to increase customer satisfaction and adapt to changing customer requirements.In recent years, identifying product features that should be enhanced or redesigned has become an essential area of study to increase product quality and decrease manufacturing costs.

Autodesk Fusion 360
Autodesk Fusion 360 is an all-encompassing 3D computer-aided design (CAD), computer-aided engineering (CAE), and computer-aided manufacturing (CAM) application.It is frequently used for product development and prototyping by engineers, designers, and manufacturers (Rahman et al., 2020;Sholeh et al., 2018) This integration ensures that the redesigned product can be efficiently produced.Overall, Autodesk Fusion 360 offers a robust set of tools and features to facilitate the product redesign process.It streamlines the entire design-tomanufacturing workflow, enabling designers and engineers to create, modify, simulate, and visualize their redesigned products efficiently.

Research Method
The research article starts with performing a literature review, including a gap to study the topic in question.This article's objectives were created after research problem defined.Then, the designing and modeling of three-wheeled cargo motorcycle were performed by utilizing Fusion 360 for design optimization.First, the product redesign is modeled using computer-aided design to create a 3D model.Moreover, Finite Element Method (FEM) simulation requires a mesh generation to numerically model the three-wheeled cargo motorcycle after the data are selected and inputted to the solver.At the next stage, the loading and boundary conditions are needed to be defined before the FEM is performed.The obtained results are verified to ensure the generated results from the FEM method.The overall research flowchart is portrayed in Figure 1.

RESULT AND DISCUSSION
Fusion 360 allows for the import of geometric models created by CAD to perform finite element analysis on static structures, dynamic features, etc. DFR analysis will be performed by structural analysis via Fusion 360.The driven optimization feature can generate analysis and optimization for deterministic designs.A typical analysis feature is the model's size, such as volume, moment of inertia, clearance, etc. Product design exploration will provide performance analysis for design optimization based on the results of the analysis of several parts of the design to find design variable values.

Analysis of Existing Product Design
The vehicle is one of the means of transportation humans use to meet their needs.As a means of transportation, vehicles must provide safety and comfort for motorists.The development of technology and science, along with the increasing human need for means of transportation, has made people more selective in choosing vehicles according to their needs.The development of the automotive world has been very rapid lately, and manufacturers are continuously trying to improve the quality of their products to meet consumer desires and compete in the market (Juniani et al., 2021).Today, many three-wheeled motorcycles are developing by adding an open bed at the rear.
The three-wheeled cargo motorcycle (see Figure 2) shows that motorcycles as public vehicles have more functions as a means of transportation.Design engineering on motorbikes such as threewheeled cargo motorcycle has the effect that the stability of these vehicles is different from motorbikes in general.Therefore, structural analysis in redesigned products is essential to ensure product strength, stability and reliability.to the entire surface of the body frame, with a load of 509.8 kg, which is assumed to be the maximum load that a three-wheeled cargo motorcycle can generally accept.The loading position and size can be seen in Figure 2. The support is given to the steering wheel and the two shock breaker brackets with a patented fixed type on the X, Y, and Z axes, which means that the three-wheeled cargo motorcycle frame cannot move towards the X, Y, and Z axes.Moreover, the type of pedestal can be seen in Figure 3.The loading Position in Figure 2 is given to all faces on the body frame; the load given is 509.8 kg, likened to the maximum load tricycle can generally accept.The loading position and size can be seen in Figure 3.The support is given to the steering wheel and the two shock breaker brackets with a fixed type which means they are patent with the X, Y, and Z axes, which means that the threewheeled motorcycle frame cannot move towards the X, Y, and Z axes.The position and type of support can be seen in the Figure 5.The mesh used is Model-based Size with a size of 5% to make it easier for the user to conduct the analysis process (see Figure 4).The analysis results in Figure 6 obtained a 4.9 in safety factor, with the critical point between the body frame and the front frame and a maximum stress of 50.4 MPa in the body frame area.Stress analysis is allowed using the following equation: So the stress value from the analysis using the software is said to be failed or unsafe if the stress value exceeds 198,5 MPa.The stress for the existing product is safe because it has a value of 50,4 MPa, which is less than the allowable stress testing.

Utilizing Fusion 360 in Product Redesign Simulation
Determining the geometric model is the first step in product redesign testing.A geometric representation method designed using a 2D or 3D approach.In this test, this research used a 3D approach.Since the body frame structure in the existing product geometry model had design flaws, removing the body's bottom frame and altering the front frame's profile dimensions were the results of this test (see Figure 7).The geometry model will be divided into finite elements in the meshing process.Excellent meshing is very important because it can affect the accuracy and efficiency of the analysis.In the load and boundary stage, determining the boundary conditions and describing the restrictions or requirements applied to the boundary points of the structure are to be analyzed.Select and identify the relevant boundary points in the structural model.Once the boundary conditions have been determined, the values and parameters of the boundary conditions must be determined.Fixed restrictions are restrictions on translational, rotational, or both movements.In this analysis, the limitations can still be seen in Figure 8 and Figure 9.All fixed limitations for type of U x , U  , and U z .In this analysis, selecting suitable material is crucial for accurate and relevant results.The selection of this material involves considering the characteristics of the material that are relevant to the analysis and then inputting the material data.The materials and data used in this analysis can be seen in the Table 2.The analysis results are obtained in the form of structural response which includes safety factor, stress, deformation, and displacement.Following are the results of the analysis of the three-wheeled cargo motorcycle frame structure.
Figure 10.Safety Factor The analysis results are obtained through structural response, including safety factors, stress, deformation, and displacement.A safety factor is a concept used to evaluate the safety and reliability of a structure.The safety factor describes the ratio between the strength or capacity of a structure with the applied load.The analysis results obtained a safety factor 3.99 with a critical point in the engine frame area (Figure 10).The maximum stress is identified to understand the level of strength and risk of failure of a structure.The visualization of the analysis results shows that the areas in the structure experiencing the maximum stress (Figure 11) are marked in red or yellow.If the maximum stress exceeds the strength limit of the structural material, then there is a risk of failure of the structure.The analysis obtained a maximum stress of 62.2 MPa with a critical point in the body frame area.
Total displacement refers to the change in position or overall deformation of a structure under load.Information about the total displacement is vital in evaluating a structure's stability, durability, and performance.Excessive or poorly distributed total displacements may indicate a problem in the structural design.The analysis results obtained a total displacement of 0.1419 mm, with a critical point between the body and front frames as seen in Figure 12.CONCLUSION This research utilizes Autodesk Fusion 360 to strengthen product design simulations.The argument for using Autodesk Fusion 360 for CAD/CAM modelling is that this tool can combine engineering and analysis tools on a single platform, increasing efficiency and simplicity in collaborative product design development.CAE studies were performed on the bracket using Autodesk Fusion 360 to simulate its performance under realistic loading conditions and constraints, enabling the determination of stresses, displacements, and safety factors.Autodesk Inventor is extremely useful for product design, tooling, mechanical design, and simulation.
Using the 3D design model of the frame of a three-wheeled cargo motorcycle, a size optimization design was performed to enhance frame strength, and the following results were obtained.The loading and boundary conditions for the frame of a three-wheeled cargo motorcycle took into account the weight of the driver and cargo, as well as the motion conditions that may occur during straight-driving and curve-driving.Structural analysis during the design stage results the assessment of three-wheeled cargo motorcycle in terms of their durability and mechanical resistance is possible without putting the user at risk.Increasing the thickness of the bracket through size optimization had the greatest impact on enhancing the longitudinal bending and torsional strength of the frame of a high-load three-wheeled cargo motorcycle.
