CSWP Motion Studies 2 — Questions and Answers
Question 1: In a SOLIDWORKS Motion Study, what is the purpose of the 'Interpolation Mode' setting on a key point?
- Controls the frame rate of the animation
- Defines how motion transitions between key points (e.g., linear vs. ease-in/ease-out) (Correct answer)
- Sets the color of the motion path in the viewport
- Determines the number of sub-steps the solver uses
Correct answer: Defines how motion transitions between key points (e.g., linear vs. ease-in/ease-out)
Interpolation Mode defines the mathematical curve used to transition component positions or values between key points.
Question 2: Which Motion Study type allows you to define a motor with a specific torque value and compute the resulting motion?
- Animation
- Basic Motion
- Motion Analysis (Correct answer)
- Exploded View
Correct answer: Motion Analysis
Motion Analysis (requiring the SOLIDWORKS Motion add-in) supports torque-driven motors and accurate physics-based simulation.
Question 3: When adding a 'Rotary Motor' in a Motion Analysis study, which parameter controls how fast the motor spins?
- Displacement
- Velocity (Correct answer)
- Acceleration
- Power
Correct answer: Velocity
A Rotary Motor's speed is specified as an angular velocity (e.g., RPM or deg/s) under the Velocity parameter.
Question 4: What does the 'Contact' feature in Motion Analysis prevent between two solid bodies?
- Interpenetration (one body passing through another) (Correct answer)
- Rotation about a shared axis
- Gravity from acting on either body
- Redundant mates from being applied
Correct answer: Interpenetration (one body passing through another)
Contact in Motion Analysis enforces collision detection so bodies cannot occupy the same space.
Question 5: In the Motion Study timeline, dragging a key point horizontally changes which property?
- The component's position at that key
- The time at which that key occurs (Correct answer)
- The interpolation mode of the key
- The solver step size near that key
Correct answer: The time at which that key occurs
Dragging a key point left or right along the timeline shifts when that recorded state occurs in the simulation.
Question 6: What is a 'spring' element used for in a SOLIDWORKS Motion Analysis study?
- To lock two components together rigidly
- To apply a variable force based on displacement between two points (Correct answer)
- To define a prescribed linear velocity
- To set a constant gravity vector
Correct answer: To apply a variable force based on displacement between two points
A spring element applies a force proportional to its extension or compression (F = k·x) between two attachment points.
Question 7: After running a Motion Analysis, where can you view a plot of joint reaction forces over time?
- In the FeatureManager Design Tree under Mates
- In the Results and Plots PropertyManager within the Motion Study (Correct answer)
- In the Simulation Advisor dialog
- In the Part document's Mass Properties
Correct answer: In the Results and Plots PropertyManager within the Motion Study
The Results and Plots tool in Motion Analysis lets you graph forces, displacements, velocities, and accelerations at any joint or body.
