Modeling a Hollow Shaft Using Simscape Multibody
8 views (last 30 days)
I am trying to model a hollow shaft using MATLAB Simscape. I read the "Compound inertia" article in MATLAB help.
It says that one of the approaches to model a hollow shaft is to use two Cylinder Solid blocks. By setting the density of one of the two blocks to a negative value, a subtraction will be made and a hollow shaft will be modeled.
I am trying to use this specific approach, however, I don't get a hollow shaft in the Mechanics Explorer. I have attached my Simulink model, Solid blocks properties, resulted model in Mechanics Explorer and the "Compound inertia" help article as pictures. Anyone knows why I don't get a hollow shaft in the Mechanics Explorer?
