Flexible Body Models in Simscape Multibody

Lumped parameter and state-space methods for static, modal, and dynamic analysis
3.8K Downloads
Updated 6 Dec 2023
Please note -- in MATLAB R2018b and higher there are blocks that ship with Simscape Multibody for flexible body modeling. Please refer to:
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.
Please read the README.md file to get started.
