摘　　要：以某轿车的ABS系统液压管路为研究对象,针对ABS调节过程中管路中的液流是非恒定流的特点,采用非恒定流摩擦损失受速度变化影响模型建立仿真模型并分析其压力传递特性,提高了仿真分析结果的准确性。An ABS hydraulic line was taken as research subject. Considering its non-steady current features in ABS regulating process, a non-steady friction model affected by speed was adopted to form simulation model, and its pressure translation characteristics was analyzed. The resulsts show that this mothod can improve simulation accuracy.
