摘要: 建立了米轨迫导向转向架客车的动力学模型,提出了迫导向机构的等效处理方法,以研究迫导向转向架 导向机构参数对客车动力学性能的影响。计算结果表明,增大迫导向机构刚度和增益有利于提高蛇行失稳临界 速度和曲线通过能力;连杆间铰链的间隙则对迫导向机构的性能有明显不利的影响。Abstract: A dynamic model for the meter-gauge passenger car with forced-steering bogies is built, in which some effective treatment methods of the forced-steering mechanism are presented, and the effect of the mechanism parameters of the forced-steering bogies on the dynamic performances of the passenger car is investigated. It is shown that the forced-steering bogies not only improve the critical speed against hunting instability, but also improve the curve negotiating ability of cars
