| 摘 要： | 为了了解车辆从直线进入曲线时的力学行为，研究了车辆系统曲线通过稳态解(平衡点)．采用延续计算的DERPAR算法，使稳态解的计算从直线经缓和曲线到圆曲线能够一次连续完成，提高了计算效率．所求得的稳态解不含瞬态成分，能更明显地揭示系统参数对车辆的某些力学行为的本质影响，为车辆系统设计参数的选取提供理论依据．

Continuous Calculation of Steady-State Solutions for Railway Vehicle Curve Negotiation |
| |
| Abstract: | In order to better understand the mechanical behavior of railway vehicles from a straight track into a curved track, the steady-state solutions(equilibrium p oints) of a vehicle system are investigated. By using the DERPAR algorithm, the numerical calculation of steady-state solutions of a vehicle system from a str aight track through a transitional track to a constant radius curved track is co ntinuously accomplished, and the calculation efficiency is improved. And the ste ady-state solutions obtained by using the DERPAR algorithm do not contain trans ient components. Therefore, the influence of the parameters of a vehicle system on its dynamic behaviors can be clearly presented. The research lays the theoret ical foundation for the design of the system parameters. |
