Exercice à faire sur Fusion 360 - Simulation Resistance de Porte Montre EX15

Introduction

This tutorial guides you through a hands-on exercise using Fusion 360, focusing on simulating the resistance of a watch case (EX15). Fusion 360 is renowned for its intuitive interface, making it an excellent choice for both beginners and professionals in the 3D modeling and design industry. By following this guide, you'll gain practical skills in simulation and design that are applicable in many engineering fields.

Step 1: Setting Up Your Project

• Open Fusion 360.
• Create a new project by clicking on the "New Project" button.
• Name your project "Watch Case Simulation" for easy identification.
• Save your project to ensure no progress is lost.

Practical Tips

• Organize your project folder to include subfolders for models, simulations, and drawings.
• Familiarize yourself with the Fusion 360 interface, including the toolbar, browser, and canvas.

Step 2: Designing the Watch Case

• Start a new sketch on the top plane.
• Use the rectangle tool to create the profile of the watch case.
• Dimension your sketch correctly using the dimension tool to ensure accurate sizes.
• Once the sketch is complete, extrude the profile to give it thickness.

Common Pitfalls to Avoid

• Ensure all dimensions are fully constrained to avoid unexpected changes in the design.
• Double-check the extrusion thickness to match your design specifications.

Step 3: Creating the Simulation Setup

• Navigate to the "Simulation" workspace within Fusion 360.
• Click on "New Study" and select "Static Stress" from the options.
• Define the model you want to simulate by selecting the watch case design you created.

Important Considerations

• Make sure to apply the correct material properties to your model. You can do this by selecting "Material" and choosing an appropriate material for the watch case.

Step 4: Defining Loads and Constraints

• Set up constraints by selecting fixed supports where the watch case will be mounted.
• Apply loads to your model that represent realistic forces it might encounter during use.
  • For example, consider adding a downward force to simulate the weight of the watch.

Step 5: Running the Simulation

• Once loads and constraints are defined, click on "Solve" to run the simulation.
• Monitor the process in the simulation timeline to ensure it completes without errors.

Practical Tips

• Review the simulation settings to ensure accuracy before running it. Adjust mesh settings if necessary for better precision.

Step 6: Analyzing Results

• After the simulation completes, analyze the results by reviewing stress distribution and deformation patterns.
• Use the visual tools provided by Fusion 360 to evaluate critical areas that may require design adjustments.

Key Metrics to Focus On

• Maximum stress points
• Total deformation of the watch case
• Safety factors to ensure design reliability
