Understanding Motion Analysis in SolidWorks
What is Motion Analysis?
Motion analysis in SolidWorks allows users to simulate the physical behavior of assembly components. It assists in understanding how parts interact under various conditions, such as movement, load, and constraints. By simulating motion, engineers can identify potential issues, optimize designs, and ensure that components function as intended.
Types of Motion Analysis
SolidWorks offers several types of motion analysis, including:
1. Basic Motion: Utilizes simplified physics to simulate the motion of assemblies without deep physics calculations. Suitable for quick checks.
2. Motion Simulation: A more detailed analysis that includes forces, accelerations, and collision detection. This is ideal for complex assemblies that require accurate physics.
3. Animation: While not a precise analysis tool, animation allows users to create visual presentations of how assemblies move, which can be useful for demonstrations and presentations.

Step-by-Step Motion Analysis Tutorial
Step 1: Setting Up the Assembly
1. Open Your Assembly: Launch SolidWorks and open the assembly model you want to analyze.
2. Check Mate Conditions: Ensure all components are properly mated. Misaligned parts can lead to inaccurate results.
3. Identify Moving Parts: Determine which parts will be moving and which will be stationary.
Step 2: Defining Motion Parameters
1. Navigate to the Motion Manager located at the bottom of the SolidWorks window.
2. Right-click on the Motion Study tab and choose New Motion Study.
3. In the Motion Study dialog, select Motion Analysis from the drop-down options.
Step 3: Adding Motors and Forces
1. Add Motors:
- Click on the Motor icon in the Motion Manager.
- Select the component that will be driven by the motor.
- Define the motor type (e.g., rotary or linear), speed, and direction.
2. Add Forces:
- Click on the Force icon.
- Select the component to which you want to apply the force.
- Input the magnitude and direction of the force.
Step 4: Setting Up Motion Study Parameters
1. Define the Time Duration for the simulation in the Motion Manager.
2. Set Gravity if applicable by clicking on the Gravity icon and specifying the direction and magnitude.
3. Adjust the Solver Settings to refine the accuracy of the simulation (e.g., setting the number of iterations).
Step 5: Running the Simulation
1. Click the Calculate button in the Motion Manager.
2. SolidWorks will run the simulation based on defined parameters.
3. Monitor the progress bar and wait for the simulation to complete.
Step 6: Analyzing Results
1. Once the simulation finishes, you can view the results in the Motion Manager.
2. Utilize the following tools to analyze the data:
- Graphs: Display forces, torque, displacement, and other metrics over time.
- Animation: Play the simulation to visualize the motion.
- Results Summary: Review overall performance, including collision detection and interference.
Step 7: Optimizing the Design
Based on the analysis results, consider making the following adjustments:
- Modify component sizes or shapes to reduce stress concentrations.
- Adjust motor speeds or forces to optimize performance.
- Reconfigure mates or constraints to improve motion efficiency.
Tips for Effective Motion Analysis
- Start Simple: Begin with simplified assemblies to become familiar with the motion analysis tools before tackling complex models.
- Use Subassemblies: Break down complex assemblies into smaller subassemblies for easier management and analysis.
- Check for Interferences: Utilize the interference detection feature to identify potential collisions before running the motion analysis.
- Document Findings: Keep thorough records of settings and results to refer back to in future projects or iterations.
- Iterate: Don’t hesitate to run multiple simulations with different parameters to explore various scenarios and outcomes.
