Solidworks Simulation and Analysis 2 — Questions and Answers
Question 1: In SolidWorks Simulation, what is a 'Thermal Study' used for?
- Analyzing stresses caused by vibration
- Calculating temperature distribution and heat flow through a part (Correct answer)
- Simulating fluid flow around a component
- Determining the natural frequencies of a part
Correct answer: Calculating temperature distribution and heat flow through a part
A Thermal Study computes steady-state or transient temperature distributions and heat flux through the model.
Question 2: What does 'Mesh Refinement' in SolidWorks Simulation do?
- Smooths the visual surface of the mesh display
- Increases the number of elements in specific areas to improve solution accuracy (Correct answer)
- Reduces computation time by coarsening the mesh globally
- Applies a higher-order material model to the mesh
Correct answer: Increases the number of elements in specific areas to improve solution accuracy
Mesh Refinement adds smaller, more numerous elements to high-stress or curved areas to improve result accuracy.
Question 3: Which SolidWorks Simulation contact condition allows two surfaces to push against each other but not pull apart?
- Bonded
- No Penetration (Correct answer)
- Allow Penetration
- Shrink Fit
Correct answer: No Penetration
No Penetration contact allows components to press together and transmit compressive forces, but they can separate freely.
Question 4: What does the 'Displacement' result plot show in SolidWorks Simulation?
- The direction and magnitude of applied forces
- The amount each node in the mesh moves from its original position under load (Correct answer)
- The temperature change across the part
- The fatigue cycles remaining before failure
Correct answer: The amount each node in the mesh moves from its original position under load
The Displacement result displays how much each point of the model deflects in response to the applied loads and fixtures.
Question 5: In SolidWorks Simulation, which fixture type allows a face to move freely in one direction while fixing all others?
- Fixed Geometry
- Roller/Slider (Correct answer)
- Reference Geometry
- Symmetry
Correct answer: Roller/Slider
Roller/Slider allows a face to slide in one direction (perpendicular to the fixture) while preventing motion in other directions.
Question 6: What is the purpose of a 'Fatigue Study' in SolidWorks Simulation?
- Checks if the part will fail under a single large load
- Predicts how many load cycles the part can endure before developing a crack or failure (Correct answer)
- Calculates steady-state temperatures from repeated heating
- Determines the resonant frequency under cyclic loading
Correct answer: Predicts how many load cycles the part can endure before developing a crack or failure
A Fatigue Study uses S-N (stress vs. cycles) curves to predict the life of a component under repeated loading conditions.
