摘要
具有防抱死能力的液压盘式制动器在轨道车辆中得到越来越多的应用。基于防抱死制动系统工作原理,利用AMESim软件内置的数据库搭建仿真模型,针对不同的液压管路特性,计算出管道材料与长度与液压制动系统的影响。结果表明,管路越长、材料刚度越小,轮缸压力响应越慢。为提高防抱死系统的控制精度,在布置防抱死系统的压力调节单元时,应尽可能地靠近制动钳,以减少管道内油液的影响。
The hydraulic disc brake with anti-lock capability has been more and more applied in rail vehicles.Based on the working principle of anti-lock braking system,the simulation model is built by using Signal and Control Library of AMESim,and the influence of pipeline material and length on hydraulic braking system is calculated according to the characteristics of different hydraulic pipelines.The results show that the longer the pipeline and the smaller the stiffness of the material,the slower the pressure response of the cylinder is.In order to improve the control accuracy of anti-lock braking system,when arranging the pressure regulating unit of the ABS system,the brake caliper should try to be approached as far as possible,so as to reduce the influence of the oil in the pipeline.
