This set of files contains a library and examples that show how to model flexible bodies using Simscape Multibody.

Please note that the General Flexible Beam block was added in R2018b and the Reduced Order Flexible Solid block was added in R2019b. You should see if these blocks meet your needs before using this library

Two methods are shown:

1. Lumped parameter method Flexible body is modeled using a chain of mass-spring-dampers. User specifies material, beam cross-section, and number of flexible elements in the chain.

2. Finite element import method Flexible body is modeled by superimposing deflection on rigid body motion. Additional degrees of freedom are added to the rigid body, and the force resisting that deflection is calculated using mass and stiffness matrices which are often exported from finite element software

Open Flexible_Body_Library.prj to get started See the examples to understand how the blocks are used.

######### Release History #########

v4.0 Mar 2018 (R2019b)

1. Updated for R2019b. Uses MATLAB Project

v3.4 Mar 2018 (R2018b)

1. Updated for R2018b

v3.3 Mar 2018 (R2018a)

1. Updated for R2018a

v3.2 Oct 2017(R2016b - R2017b)

1. Damping parameterized with damping factor Replaced damping coefficient parameter in lumped parameter beam with damping factor. This permits damping value to scale with geometry and material. Damping coefficient entered in flexible elements = (damping factor*stiffness).

v3.1 Sept 2017 (R2017b)

1. Updated for R2017b

v3.0 June 2017 (R2017a)

1. New models and library
2. Version number set to match File Exchange
3. Library with Lumped Parameter and Finite Element Import beam models Two cantilever beam examples and a Slider-crank example are included
