1. Watch the videos
Dassault Systèmes videos hosted on MySolidWorks: they open in a new tab and a free account is enough. Watch them in order.
Introduction to Dynamic SimulationThe dynamics module and the studies suited to each type of time-varying load.↗ Dynamic Simulation SetupNatural frequencies, mass participation factor and comparison between a slow and a fast force.↗
2. Key takeaways
A load applied slowly can be calculated as static; a fast load can excite the structure and give a much larger response.
Dynamic studies rely on the natural frequencies: you must calculate enough of them to represent the response.
The mass participation factor tells you whether the number of calculated modes is sufficient.
Comparing the same force applied slowly and then quickly shows the gap between static and dynamic results.
Tip
Run a frequency study on its own before any dynamic study: you know how many modes to request and where the potentially problematic frequencies are.
