Aiming at the PK type automotive V-ribbed belt

using the CATIA software

the automotive V-ribbed belt model and the pulleys 3D model is created

automotive V-ribbed belt mesh is based on the ANSYS software

and imports into the multi-body dynamics RecurDyn software to build up the dynamic simulation model of the automotive V-ribbed belt transmission through the MFBD（more flexible body dynamics） techniques.The transmission performance of the automotive V-ribbed belt

contact strength of belt surface and tension stress are analyzed.It gives the stress distribution between the belt and the gear belt

and the distribution state of the tensile stress.It provides a digital simulation analysis and design method to design the automotive V-ribbed belt shape

analysis the transmission performance

select the rubber and the powerful layer.
