摘要
基于非线性系统,针对列车连挂计算中缓冲器特性曲线分段线性化的特点,利用Newmark-β方法的基本原理重新推导计算公式,改进了传统的Newmark-β方法,改善了算法的稳定性,减小了计算误差,使之适用于列车连挂的计算。
Based on the non-linear system and in the light of the characteristics of piecewise linearization of the bumper performance curve in the calculation of train couplings, the calculation formulas are re-deduced by use of the basic principles of Newmark-β method. The traditional Newmark- β method is improved. Stability of the calculation is improved and tolerances are reduced so that the method is suitable for the calculation of train coupling.
