Abstract:

The brake sub operation which met with the characteristics of proving ground was defined, standardized and formulated to reproduce brake judder evaluation durability test at proving ground with using temperature and energy as simulation target and considering velocity and deceleration, based on the brake
energy theory, the formulization of braking process temperature transformation and the sampling data. The theoretical method for connecting brake sub operation was proposed and the simulation model for proving ground operation was built. The results show that the simulation model of brake operation is reliable, and the vehicle test operation at proving ground can meet the brake durability requirement and has the same assessment function.

Key words: brake durability test, theoretical fitting, temperature distribution, energy distribution, simulation model
