Join Tony Abbey for an in-depth discussion in this video Mass participation background, part of SOLIDWORKS Simulation: Dynamic Analysis.
- [Narrator] In this video we're going to look…at the background to mass participation.…Now we've mentioned previously that…in normal modes analysis we can't calculate…the relative amplitude of each mode.…Simply, each one is a mode shape.…To find a relative amplitude, we're gonna have…to do some kind of response analysis.…Now an exception to this is base motion.…This occurs where the structure…is connected to ground and the ground moves…or shakes and takes the structure with it.…If we assume a unit excitation on the base,…then the term called the modal effect to mass…can be calculated.…
Now SolidWorks describes this term as mass participation,…and that's the term we'll be using from now on.…Now the key thing is that mass participation,…or more commonly known as modal effective mass…is actually calculated in the normal modes analysis.…At the top here we see the mass participation table…that can be requested after we run a normal modes analysis.…The structure that the table represents…is the tray which is shown below.…
