某中置轴挂车列车制动强度试验测试研究

Test Research of Center-Axle Trailer Combination Braking Rate

近年来,中置轴挂车列车在国家相关政策法规的推动下稳健发展,中置轴挂车列车的制动性能对其安全行驶至关重要。本文选取一辆中置轴挂车列车进行制动试验,对其测量车速、制动距离、瞬时减速度、主挂间的铰接力、主车及挂车的制动气室压力等相关物理量,分析其在制动过程中的变化情况。本文为中置轴挂车列车的制动性能研究提供了数据支撑。

In recent years,the central-axle trailer combination develops steadily under the promotion of relevant national policies and regulations.The braking performance of center-axle trailer combination is crucial to the safe driving.This paper selected a center-axle trailer combination to test the braking performance,testing data such as speed,braking distance,instantaneous deceleration,thrust on the coupling and brake chamber pressure are collected,all these data are analyzed during the braking process.This paper provides data support for the research of center-axle trailer combination braking performance.
