CSWP Assembly Motion and Detection 3 — Questions and Answers
Question 1: In SolidWorks Motion Study, what does 'Animation' type allow compared to 'Basic Motion'?
- Animation supports contact and gravity forces while Basic Motion only moves mates
- Animation only moves components along mate-driven paths without physics, while Basic Motion includes approximate physics (Correct answer)
- Animation uses the SolidWorks Simulation solver while Basic Motion does not
- Animation requires a CSWP license while Basic Motion is available in all versions
Correct answer: Animation only moves components along mate-driven paths without physics, while Basic Motion includes approximate physics
Animation type moves components according to defined key positions and does not calculate physical forces, while Basic Motion includes gravity, springs, and contact approximations.
Question 2: A cam mate in SolidWorks requires which geometric elements to define the cam-follower relationship?
- Two flat faces and a coincident mate
- A cam surface profile and a follower face or point (Correct answer)
- Two cylindrical faces with the same axis
- A circular edge and a linear edge
Correct answer: A cam surface profile and a follower face or point
A cam mate requires a cam profile surface and a follower element (face or point) that remains in contact as the cam rotates.
Question 3: Which of the following correctly describes a 'Screw Mate' in SolidWorks?
- It creates a fixed threaded connection between two parts
- It couples linear translation along an axis to rotation about that same axis (Correct answer)
- It applies a torque load to a fastener during simulation
- It automatically applies a thread feature to cylindrical faces
Correct answer: It couples linear translation along an axis to rotation about that same axis
A Screw Mate links linear displacement along an axis to angular rotation about that axis, simulating helical (screw) motion.
Question 4: When using Interference Detection with the option 'Create fastener folder' enabled, what happens to detected interferences involving fasteners?
- Fasteners are deleted from the assembly
- Interference results involving fasteners are grouped separately in the results tree (Correct answer)
- Fasteners are excluded from interference detection entirely
- Fastener interferences are automatically resolved
Correct answer: Interference results involving fasteners are grouped separately in the results tree
The 'Create fastener folder' option groups fastener-related interference results into a dedicated folder in the Interference Detection results, making them easier to manage.
Question 5: In Motion Analysis, what is a 'damper' element primarily used to simulate?
- A rigid connection that prevents all motion
- A force that resists relative velocity between two components, dissipating kinetic energy (Correct answer)
- A spring that stores and releases energy
- Friction between a rotating shaft and its housing
Correct answer: A force that resists relative velocity between two components, dissipating kinetic energy
A damper element applies a force proportional to relative velocity, representing energy-dissipating behavior such as hydraulic or viscous damping.
Question 6: When running Collision Detection during a Motion Study, which solver must be active?
- Animation solver
- Basic Motion or Motion Analysis solver (Correct answer)
- Static solver
- FEA solver
Correct answer: Basic Motion or Motion Analysis solver
Collision detection during motion studies requires either the Basic Motion or Motion Analysis solver, as the Animation solver does not calculate contact.
Question 7: In a SolidWorks assembly, which mate would you use to keep a ball always tangent to the inside of a curved track surface?
- Coincident mate
- Tangent mate (Correct answer)
- Width mate
- Path mate
Correct answer: Tangent mate
A Tangent mate constrains two surfaces or edges to remain tangent, keeping the ball in continuous contact with the curved track surface.
