摘要
首次提出可以用 3个导向机构参数描述迫导向转向架的动力学性能 ,即导向增益、迫导向机构的等效导向刚度以及迫导向机构杆件的等效连接间隙 ,文中详细推导了 3个基本参数的表达式 ,并以装配迫导向转向架的米轨客车为例 ,建立了 4 3个自由度的动力学计算模型 ,讨论了 3个导向机构参数对米轨客车动力学性能的影响。
It is put forward for the first time that three parameters of the steering mechanism can be used to describe the dynamic performance of forced steering bogies, i.e., the steering gain, the equivalent steering rigidity of the steering mechanism and the equivalent connection clearance of the rods of the steering mechanism. In this paper, the expressions of three fundamental parameters are deduced, with the meter gauge passenger car equipped with the steered bogie as the example, the dynamics calculation model of 43 degrees of freedom is set up, and the effect of the three parameters of the steering mechanism on the dynamic performance of meter gauge passenger cars is discussed.
