To make the simulation of the drum brake is closer to the true state

using three-dimensional CAD modeling software CATIA

finite element analysis software Hypermesh and multi-body dynamics analysis software MSC.ADAMS

regarding cambrake plate

brake shoes and brake drums as a rigidbody

seeing brake friction plates as a flexible body

a rigid-flexible coupling dynamics simulation model of the drum is established.The real-time cam prokinetic power is provided to drum brakes finite element thermal structure coupling analysis.The dynamics simulation collar from hoof to promote the power relations is in accordance with the relevant literature

the correctness of the model is verified.The reason of brake drum is found and some improvement measures are given.
