摘要:

       为了在试车场重现考核制动抖动的制动耐久试验,基于制动能量理论分析,结合采样数据和试验结果,确立以温度和能量分布为目标的模拟要求,考虑速度、减速度等影响因素,制定了符合试车场运行特点的制动子操纵方式。在标准和公式化制动子操作的基础上,提出了连接制动子操作的理论方法,并搭建了试车场操作的仿真模型。结果表明:基于制动能量理论及公式化的制动操作温度变化方程建立的制动试验仿真模型是可行的,试车场的实车操作方法能够很好地重现制动耐久试验,具有同等的制动抖动考核功能。

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
