电脑模拟计算法是我厂在分析北京型机车横向稳定性时开发的一种新方法。此法比目前国内对两轴转向架机车采用十七个自由度求解34个特征值和特征向量的电算法简捷电算工作量小、周期短,并可直观地得出各种方案的机车横向失稳速度,对分析机车的横向稳定性具有实用价值。 Computer simulation method is a new method developed by our factory when analyzing the lateral stability of Beijing locomotives. Compared with the current domestic method of using seventeen degrees of freedom to solve 34 eigenvalues ​​and eigenvectors for a two-axle bogie locomotive, the simple and simple calculation method of electric calculation is small in workload and short in cycle, and can be intuitively obtained in various aspects of locomotive transverse directions Instability speed, the lateral stability of the analysis of the practical value.
