Dassault Systèmes videos hosted on MySolidWorks: they open in a new tab and a free account is enough. Watch them in order.
Transient Dynamic SimulationShock by base excitation, mesh optimized for dynamics and structural damping.↗ Harmonic AnalysisDefine a load in the frequency domain and use the results of the harmonic study.↗
2. Key takeaways
The transient study gives the response over time, for example to a shock applied through the base (base excitation).
Damping directly governs the amplitude of the response: without it, dynamic results are meaningless.
The harmonic study defines the load in the frequency domain and gives the response at each excitation frequency.
In dynamics, the mesh is sized first to represent the relevant modes of the structure correctly.
Tip
Record the damping value you used and its source in your report: it is the first question a reviewer will ask about a dynamic analysis.
