The development of composite friction materials, such as organically bound brake pads, is to a great extent done on the basis of experience. Material developers have very few software tools available, which support the development process with simulations and help to reduce the number of prototypes and tests.The focus of this work is on the temperature field in organic friction materials, which is...
In order to simulate the wheel wear behaviour of freight cars, the rail vehicle's multi-body dynamical model and wheel wear simulation programme were combined as a wheel wear simulation tool in this paper. Multi-body dynamical models of China's heavy haul freight cars such as the C80, C80H, C70 and C70H, were built in SIMPACK software and the track system was built based on the China's Ring-line....
Coefficient of friction is a significant factor for investigating stress and strain on the contact surface for a problem on torsional fretting wear. First, in this paper, a variable coefficient of friction model related to space and time is introduced. The evolution of friction coefficient is governed by the local contact history and the slip distance. Then, this model is implemented in the finite...
