Are you looking to validate your mechanical designs before prototyping? SolidWorks Motion Analysis is a powerful tool that allows engineers to simulate the real-world physical behavior of an assembly. In this guide, we will simplify the process of setting up a motion study to ensure your CAD models move exactly as intended.
Why Use Motion Analysis in SolidWorks?
Unlike basic animations, SolidWorks Motion Analysis accounts for physical properties such as mass, friction, and gravity. By using this tool, you can:
- Calculate motor torque and power requirements.
- Identify potential interferences during movement.
- Export load data for Structural Analysis (FEA).
Step-by-Step: Setting Up Your First Motion Study
1. Enable the SolidWorks Motion Add-in
First, ensure that the SolidWorks Motion add-in is activated. Go to Tools > Add-Ins and check the box for SolidWorks Motion. This unlocks the "Motion Analysis" option in the Motion Study tab.
2. Define Connections and Gravity
A realistic simulation requires physics. Start by adding Gravity to define the "down" direction. Next, check your Mates. SolidWorks Motion translates your assembly mates into mechanical joints automatically.
3. Apply Motors and Forces
To make things move, apply a Rotary Motor or Linear Actuator to a specific component. You can set constant speeds, oscillations, or even complex path-based movements.
4. Run the Calculation
Click the Calculate button (the gold gear icon). SolidWorks will solve the mathematical equations for every frame of the motion. Once finished, you can analyze the results using the Results and Plots tool.
Pro Tip for Accurate Results
To improve the accuracy of your CAD simulation, always ensure that your components have the correct Material Properties assigned. The weight and density of the part significantly affect the momentum and friction in your analysis.
