Mechanical Friction with Simulink and Physical Modeling

Modeling and simulating mechanical friction in the Simulink® and Physical Modeling environment

Description

Stephen Lunzman (Caterpillar), Dallas Kennedy and Steve Miller (The MathWorks)

Systems modeled include clutches, transmission, and pistons. The friction is continuous or hybrid continuous-locking type. Locking friction requires mode iteration and algebraic loops.

NOTE: If you receive MATLAB® command line warnings upon opening these models in a later version of Simulink, resave, close, and reopen the models in the later version.

• Required Products: SimDriveline; SimMechanics; Simscape; Simulink
• MATLAB release: MATLAB 7.5 (R2007b)
• Other requirements: - continuousPiston and lockingPiston depend on SimMechanics. - continuousClutch3 and multiClutch depend on SimDriveline. - JPGs needed as support files for two models - M-file script for use with continuousPiston, which must be loaded first

I believe such files can provide very good learning opportunities for me, in my quest to learn and use MATLAB.
Keep it up.
