Solidworks Simulation and Analysis 1 — Questions and Answers
Question 1: In SolidWorks Simulation, what is a 'Fixed Geometry' fixture used for?
- Applies a load in a fixed direction to selected faces
- Prevents selected faces, edges, or vertices from moving in any direction (Correct answer)
- Locks the mesh so it cannot be refined
- Sets a specific displacement on a face
Correct answer: Prevents selected faces, edges, or vertices from moving in any direction
Fixed Geometry constrains all translational and rotational degrees of freedom on selected geometric entities.
Question 2: What does a 'Von Mises stress' result in SolidWorks Simulation represent?
- The maximum normal stress in one direction
- A combined stress scalar used to predict yielding in ductile materials (Correct answer)
- The shear stress on the cross-section
- The fatigue life under cyclic loading
Correct answer: A combined stress scalar used to predict yielding in ductile materials
Von Mises stress is a single equivalent stress value combining all stress components, used to compare against the material yield strength.
Question 3: What is the purpose of meshing in SolidWorks Simulation?
- Creates a decorative surface pattern on the part
- Divides the geometry into small elements for finite element analysis calculations (Correct answer)
- Generates the wireframe display of the model
- Defines contact conditions between assembly components
Correct answer: Divides the geometry into small elements for finite element analysis calculations
Meshing discretizes the model into finite elements, enabling the solver to calculate stress, displacement, and other results.
Question 4: In SolidWorks Simulation, which study type is used to determine the natural frequencies of a part?
- Static Study
- Thermal Study
- Frequency Study (Correct answer)
- Fatigue Study
Correct answer: Frequency Study
A Frequency Study (modal analysis) calculates the natural resonant frequencies and mode shapes of a structure.
Question 5: What does 'Factor of Safety' indicate in a SolidWorks Simulation result?
- The ratio of applied load to the maximum possible load before failure
- The ratio of material yield strength to the maximum Von Mises stress (Correct answer)
- The percentage of the model that is under-stressed
- The number of load cycles before fatigue failure
Correct answer: The ratio of material yield strength to the maximum Von Mises stress
Factor of Safety is the yield strength divided by the maximum Von Mises stress; a value below 1 indicates failure.
Question 6: Which SolidWorks Simulation load type applies a force distributed uniformly over a selected face?
- Torque
- Gravity
- Pressure (Correct answer)
- Remote Load
Correct answer: Pressure
Pressure applies a force per unit area uniformly across a selected face, simulating fluid or contact pressure.
