Dynamic Analysis in SOLIDWORKS

Within the suite of tools offered in SOLIDWORKS Simulation Premium is the ability to do linear and non-linear dynamic analyses of parts and assemblies. 

Studies are often performed statically, where loading is applied gradually until the full value is reached.  This gradual loading does nothing to include the effects of inertial or damping forces.  In the real world, most loads are not gradually applied or change with time and frequency.  When analyzing this type of behavior, a linear or non-linear dynamic study should be used. 

Linear dynamic studies are based on modal or frequency studies.  SOLIDWORKS calculates the response of the model by continually accumulating the contributions of each mode in the model.  The significant contribution of a mode depends on its frequency content, magnitude, direction, duration, and location.

Typical Dynamic Loading Scenarios:

Harmonic Loading expressed as P = A sin (ωt + φ)

Random Vibration Analysis:

Random vibration analysis is used to predict the response of a structure to non-deterministic loading.  Examples of such loading are:

• Wheel loading on a vehicle moving along a road
• Base accelerations generated by earthquakes
• Pressure generated by air turbulence
• Pressure from sea waves or strong winds
