城轨车辆启动制动与乘坐舒适性实验研究分析 摘 要：我国铁路客运正迎来跨越式发展的历史机遇，追求高品质的乘坐舒适性是伴随这一发展历程的必然要求。通过对列车启动与制动时加速度与加速度的变化率对乘客乘坐舒适性的影响的实验分析得出以下结论：列车启动或制动时坐着比站着乘坐舒适度高；当乘坐姿势相同时，启动或制动的加速度越大，舒适度越低；列车启动与制动时加速度的变化率对于不同乘坐姿势的乘客的乘坐舒适度的影响较大，特别是对朝前站立和朝后站立这两种不同姿势。以上提到的加速度和加速度的变化率均在理论允许范围内。

Urban Rail Vehicle Starts Braking and Ride Comfort
Abstract: China's railway passenger is ushering in the historical opportunity of the leaps and bounds, the pursuit of high-quality ride comfort is accompanied by the development process. We can draw the following conclusions by the experimental analysis on the trains’ start and brake acceleration and the impact on passengers’ comfort by the accelerate of the rate of change: sitting is more comfortable than standing when the train start or brake; the greater the acceleration, the lower the degree of comfort when the riding postures of passengers are same; train start and braking acceleration of the rate of change have a high influence on the passengers’ ride comfort when they take different riding postures, especially two different postures: standing forward and standing rearward. The above mentioned acceleration and the acceleration rate of change are in the range of theoretical allowable.
Key Words: Start; Brake; Comfort; Acceleration; Rate of change of acceleration
