橡胶轮转向架稳态曲线通过行为研究

Research of Steady-State Curving of Rubber-Tyred Bogie

以橡胶轮转向架为研究对象 ,在分析其特殊的轮轨关系的基础上 ,建立了半车稳态曲线通过动力学分析模型 ;以轮轨横向力为优化目标 ,以轮重减载率和侧偏角为约束条件 ,确定了一、二系悬挂参数 ,并对优化值进行了参数稳定性分析 ;在此基础上 ,系统地研究了橡胶轮转向架的稳态曲线通过性能 .

An analytical modal for steady state curving of rubber tyred bogie is established with its special wheel rail relations taken into account. With the transverse wheeltrack force as optimization objective and with the deflection angle and deloading rate of wheels as the constraint condition, the primary and secondary suspension parameters are determined and their stability are also assessed.
