Braking System Analysis And Friction Interface Parameters Test

With the development of automotive industry and the transportation, the rapid ofvehicle maintain increasingly, at the same time to bring convenience, but also producean increasing number of traffic accidents, Taken to safe and reliable braking device isto ensure road safety, improve vehicle operating efficiency the important means. Thebraking performance not only influence the dynamic performance car fuel economyand play, and it is directly related to the stand or fall of safety problems. so, the theoryof tribology, vehicle brake system and vehicle braking process to conduct acomprehensive study and theoretical analysis, Using shrinkage test bench PV3212testmethod than take, in the same braking power compared and analyzed the frictionunder different radius of the influence of friction level, in order to optimize theautomobile braking system, has the positive reality significance and social benefits.Brake friction and wear at home and abroad, based on the road test and1:1bench test,while the use of scale bench test is not perfect. This test equipment with jilinuniversity institute of electrical and mechanical equipment of production JF122Cshrinkage test bench than inertia, and to design brake disc and slide machine system,In Hubei the United equation for friction material limited company in situ test, testmethods with reference to the international advanced level of the Audi PV3212standard, this standard change in radius, friction brake pressure and rotational speedand other parameters, the use of JLF language test program.The innovation of this paper is to keep the braking power constant, in differentfriction radius, different brake pressure and different speed cases, reviewing thefriction interface parameters, through the experiment data, this paper discusses thefriction parameters on the level of interface friction effects.
