作者根据我国新双层客车的结构特点,建立了横向动力性能的数学模型,校核了车体在弹簧上的倾覆稳定性,分析了车辆以不同速度通过道岔及渡线时的车体横向移动量、脱轨系数和轮重减载率。同时还估测了在线路不平顺的激扰下双层客车的随机响应。计算结果表明,新双层客车不仅满足运行安全的要求,而且具有良好的平稳性能。
Based on the structural characteristics of the new double-decker bus in our country, the author established the mathematical model of lateral dynamic performance, checked the rollover stability of the vehicle body on the spring, and analyzed the lateral movement of the vehicle body when the vehicle passed the turnout and crossing line at different speeds Amount, derailment coefficient and wheel load reduction rate. It also estimates the random response of double-decker buses under the disturbed lines. The calculation results show that the new double-decker bus not only meets the requirements of operational safety, but also has good smoothness.
