摘要
全面地考虑机车车辆的实际情况后，提出了十个等效刚度和等效阻尼的概念，导出了同时适用于常规转向架、车辆径向转向架和机车径向转向架的通用表达式，用简单、直观的状态方程统一表示这几种情况的半车模型的动力学性能方程，并与轨道参数和应用参数相结合，建立了机车径向转向架的统一等效模型，为分析机车径向转向架的内在机理和根本特性以及进行参数分析和参数优化提供了方便有效的工具。
In this paper,ten equivalent stiffness and damping concepts are proposed and their expressions are derived for conventional bogie and radial bogie.A simple and united constitute equation is introduced to describe the dynamics characteristic for these bogies.Combining this constitute equation with the rail parameters and service condition,we can therefore develop a united equivalent model.Applying this model,it is convenient to analyze the inherent mechanism and foundational property,and optimize the parameters of radial powering bogie.
