因为轨道交通车辆制动冲击暂时没有统一的评价方法,分析标准中平均冲击和瞬时冲击的定义以及制动过程中制动冲击产生的情况,确认采用瞬时冲击作为制动冲击评价对象更能反映制动冲击的变化情况,同时对于《铁路应用-乘客乘坐舒适度-测量与评价》BS EN 12299-2009中提出的横向瞬时减速度一阶导数数据分析方法进行分析和提炼,提出制动冲击的数据分析方法.
Because there is currently no unified evaluation method for the braking impact of rail transit vehicles,this article ana-lyzes the definitions of average jerk and instantaneous jerk in the standards,as well as the situation of braking jerk generated dur-ing the braking process.It is confirmed that using instantaneous jerk as the evaluation object of braking jerk can better reflect the changes in braking jerk;at the same time,an analysis and refinement of the first-order derivative evaluation method for lateral in-stantaneous deceleration proposed in the standard Railway Applications-Passenger Riding Comfort-Measurement and Evaluation are conducted,and a braking jerk evaluation method is proposed.
