Flexible bodies via lumped parameter and finite element data for static, modal, and dynamic analysis

Updated 18 Apr 2019

This file contains flexible beam models implemented in Simscape Multibody that use lumped parameter and finite element data approaches. It includes methods to compute static deflection, natural frequencies, plot mode shapes, and obtain the state-space representation from lumped parameter model.

A second question please. I have tried to use the LPM method but my beam segment gets distorted in the configuration where it is connected to other bodies. When I simulate the beam alone, everything works fine. But on connecting to the multibody structure, it gets distorted at the points where the revolute joints are located. What could be responsible? How can I solve? Thanks

I noted the new flexible beam capability in SimScape Multibody. Will there be any more information on how we can implement our own beam models in a similar way? I want to incorporate a nonlinear beam model.

Just a quick question : How can I define the two end points as fixed point ?
