米轨客车迫导向转向架动力学性能研究

Dynamic Performances of Meter-Gauge Passenger Car with Forced-Steering Bogies

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。

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.
