In order to build a basic high power density friction plate（ vice） procedural design model,forming a fairly complete friction plate（ vice） design system,a comprehensive friction and wear performance design and friction plate mechanical strength design engineering system design method is presented based on actual experience considered a critical dimension tolerance design,the design suitable for high power density of the engine compartment with a friction plate design is summed up as friction and wear property of design and friction plate mechanical strength design two aspects,through linking with friction plate test design parameter library of the corresponding parameter,a technology platform of bearing friction plate design,research is established,it is improved the design precision and efficiency greatly.
