机车运行时的横向稳定性计算,是机车动力学主要计算之一。计算时首先确定机车运行的临界速度,即机车维持稳定运行的最高速度,这是评定机车运行性能优劣的一个重要指标。这个问题,从力学上分析是一个机械系统自激振动的稳定性问题;按数学观点则是一个常微分方程组的稳定性判别问题。本文对韶山4型电力机车横向稳定性进行了计算。计算中采用直接法。结果表明,这种方法不仅能适用微型机计算,而且有良好的技术经济效果。
The calculation of the lateral stability of locomotive running is one of the main calculations of locomotive dynamics. First of all, when calculating, the critical speed of locomotive running is determined, that is, the maximum speed at which locomotives maintain stable operation, which is an important index to evaluate the locomotive performance. This problem, from the mechanics analysis is a mechanical system of self-excited vibration stability problem; according to the mathematical point of view is a differential equation stability of the problem. The paper calculates the lateral stability of Shaoshan 4 electric locomotive. Calculation using direct method. The results show that this method not only can be applied to microcomputer calculation, but also has good technical and economic effects.
