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 the characteristics of piecewise linearization of the buffer characteristic curve in the calculation of train link-up, the Newmark-β method is used to derive the calculation formula again and the traditional Newmark-β method is improved to improve the stability of the algorithm , Reducing the calculation error, making it suitable for train linked to the calculation.
