Design and Simulation Analyses of Dynamic Testing Devices for Automobile Braking Performance

The technical requirements for automobile braking systems,braking performance testing indexes,currently existing braking performance testing methods and the problems with testing equipment are analyzed,the design concept of a dynamic testing system is presented,a dynamics model when an automobile brakes under this system is established and Matlab is used to simulate the model to further show that not only the dynamic shaft weight but also the static shaft weight of automobiles should be tested when carrying out braking performance tests,which provides an adequate theoretical basis for automobile braking performance tests.
