车钩间隙 meaning in English

coupler slack

This paper uses the program to calculate the dynamics performance of small slack coupler that designed by qiqiha ' er vehicle ( grounp ) company . by compared maximum coupler force and maximum acceleration of car body with common slack coupler at condition of train starting , braking , emergency braking and releasing , we verified that small slack coupler is better than common slack coupler in dynamics performance . this paper also calculated the train dynamics performance parameter with different buffer and braking system , running in different line and using different operating method
本文利用列车纵向动力学模拟程序，计算了齐齐哈尔车辆(集团)公司研制的13号小间隙防脱车钩的纵向动力学性能，通过比较各个车钩间隙下列车最大纵向车钩力和列车最大加速度的数值，得出小间隙车钩在列车启动工况、常用制动工况、紧急制动工况、缓解工况的纵向动力学性能都较原有车钩性能优异的结论。
