Power Transmission Using Pulley Networks

Best practices for modelling Simscape™ Driveline™ pulley systems

The Simscape Driveline Couplings and Drives library includes pulley blocks that allow you to transmit power. The Belt Pulley block represents a simple belt-driven friction pulley. The Belt Drive block combines two Belt Pulley blocks that you can configure as an open or crossed belt system. You can model a simple hoist using the Belt Pulley. To model more complex mechanisms, combine several pulley blocks with tensioners, which you build using springs and dampers. Build high-fidelity models by including other Simscape and Simscape Driveline blocks.
