Solidworks Simulation and Analysis

Question 1

In SolidWorks Simulation, what is a 'Fixed Geometry' fixture used for?

Accepted Answer

Prevents selected faces, edges, or vertices from moving in any direction

Answer

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?

Accepted Answer

A combined stress scalar used to predict yielding in ductile materials

Answer

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?

Accepted Answer

Divides the geometry into small elements for finite element analysis calculations

Answer

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?

Accepted Answer

Frequency Study

Answer

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?

Accepted Answer

The ratio of material yield strength to the maximum Von Mises stress

Answer

Factor of Safety is the yield strength divided by the maximum Von Mises stress; a value below 1 indicates failure.
