【摘要】 惯容器作为一种新型结构控制元件被广泛应用于结构振动系统中，但在转向架电机悬挂中却研究较少。建立3种惯容器-刚度-阻尼(inerter-stiffness-damping, ISD)电机架悬转向架横向动力学模型，采用光滑拟合曲线模拟等效锥度，用实测轨道谱作为转向架系统激励输入，以构架端部加速度滑移均方根综合值作为优化目标函数，通过减法平均优化器优化算法对ISD架悬参数和原有刚度-阻尼(stiffness-damping, SD)结构参数进行优化并分析其稳定性。结果表明，ISD串并联结构降低转向架振动响应效果最好，在新轮新轨匹配和车轮镟修后期条件下，其稳定性最佳，线性临界速度较SD结构可提升215.6 km/h。ISD三并联结构各稳定性指标略低于SD结构，而ISD三串联结构会恶化转向架横向稳定性，降低其临界速度，同时，其综合均方根和最大均方根对速度变化最敏感，不利于改善转向架横向稳定性。研究结果可为高速动车组电机弹性架悬设计提供参考。更多还原

【Abstract】 Inerters are widely used as a new type of structural control element in structural vibration systems, but are less studied in bogie motor suspensions. Three kinds of lateral dynamics models for an inerter-stiffness-damping(ISD) motor frame suspension bogie were established. The equivalent conicity was simulated by smooth fitting curves, the measured track spectrum was used as the excitation input of the bogie system. The integrated value of the root-mean-square of the acceleration at the end of the frame was used as the optimization objective function. The parameters of the ISD frame suspension and the original stiffness-damping(SD) structure were optimized and their stability was analyzed by using the subtractive averaging optimizer optimization algorithm. The parameters of the ISD frame suspension and the SD were optimized through the subtractive average optimizer algorithm and their stability was analyzed. The results show that the ISD tandem-parallel structure has the best effect in reducing the vibration response of the bogie, and its stability is the best in the condition of new wheel-rail matching and being in the late stage after wheel reprofiling, and its linear critical speed can be increased by 215.6 km/h compared with that of the SD. The ISD triple-parallel structure has the stability indexes slightly lower than that of the SD, and the ISD triple-tandem structure deteriorates the lateral stability of the bogie and reduces its critical speed. At the same time, its integrated root-mean-square and maximal root-mean-square are lower than that of the SD. Its integrated root-mean-square and maximum root-mean-square are the most sensitive to speed changes, which is not conducive to improve the lateral stability of the bogie. The results provide a reference for the design of motor elastic suspensions used in high-speed EMUs.更多还原
