ABSTRACT
The testing of the automobile brake performance is one of important parts in Vehicle safety the amount of the automobile increasing rapidly in our nation, the affect of automobile to the environment is concerned by more and more people. The brake performance of automobile has the relation with the safety of people. Therefore, it is necessary to find best methods and tools of testing automobile brake performances quickly and accurately. The paper is the research of key technology in automobile brake ,the paper give a brief introduction about present automobile brake tester and future tendency in the paper analyzes the process of the braking of auto, and present the methods of testing brake performance, compares the advantages and disadvantages of various testing methods, discusses the criterions of assessing brakep erformances and national goes dynamic analysis of braking automobile on the tester,explains the principle of testing automobile brake performance,analyzes the main factors for brake analyses the total construction of the drum type automobile brake tester, gives the methods of choosing the sizes, speed,surfaces material of tester drums,as well as reasons of choosing tester motor,
