RESEARCH ON DESIGN METHOD OF A
MULTIPLE DISC WET BRAKE IN LUBRICATED ENVIRONMENT*
Abstract:
The rmomechanical phenomena occurring between friction pairs greatly change the distributions of lining pressure and friction surface temperature of a multiple disc wet brake. It has become one of the main causes of brake failure. In order to understand these thermomechanical phenomena, several design and material factors that have great influence on thermomechanical
phenomena, such as heat transfer coefficient, friction factor,
sliding velocity, initial lining pressure and so on, are
analyzed. An isothermal design method is proposed for designing
a multiple disc wet brake.
