摘要
分析了缓冲器特性、制动缸充气特性、制动波速等影响列车纵向运行品质的关键因素。在分析列车运行时纵向所受到各种作用力的基础上,初步探讨了列车纵向动力学的数学模型及其数值算法。利用该模型仿真求出的加速度及冲动值大小与我们以前试验所测结果基本相符。
The important factors of affecting train's longitudinal riding quality, including bumper's character, brake cylinder's character and braking wave,are analyoed, on the basis of longitudinal force being analyzed, the mathematical model of train's longitudinal dynamics and its arithmetic are dcscussed in the paper. Using the mathematical model of train's longitudinal jerk dynamics, the values of acceleration and jerk of a train are obtained, and the value accords with our test result made previously.
