摘 要: 基于VABCO压力调节器气制动ABS系统,综合考虑温度、管路长度等影响因素建立了制动气室压力变化数学模型;通过压力阶跃响应试验,频率特性试验和PWM调压试验分析了制动压力动态特性,证明了所建立的数学模型基本合理,为ABS控制逻辑的开发提供了理论依据。 The mathematic model of the braking pressure characteristics is set up considering factors concerned such as the temperature and pipeline length based on the VABCO ABS. Through the test of pressure step response, the test of the frequency characteristics and PWM pressure modulation test, the dynamical properties of the braking pressure is analyzed, which proves the rationality of the mathematic model built and provides the theoretical basis for ABS control logics.
