【摘要】 针对HX_D2型重载机车牵引试验中安全性指标超限的问题,对DFC-E100型钩缓装置及其原型车钩受纵向制动压力下的作用原理进行了分析,根据DFC-E100型钩缓装置的试验数据建立了车钩动力学模型,并将其应用到两台HX_D2机车牵引重载列车的分析模型中,对承受纵向压力时重载机车的动力学问题进行研究。结果表明大摆角车钩必须具有对中复位功能;纵向压钩力和对中复位功能对机车轮缘磨耗有显著影响。更多还原

【Abstract】 Aiming at the problem of safe performance indexes over - limitation in the traction test of HX_D2 heavy - load locomotives,the paper tells how to establish the dynamic model,which is based on the test data,of DFC - E100 coupler draft gears,by analyzing the operation principle of DFC - E100 coupler draft gears and its prototype couplers while bearing longitudinal compressive strength.And it also introduced how to apply the model to the analyzing model of the heavy - load train drove by two locomotives,and analyzes the dynamics problems of the heavy - load locomotive bearing longitudinal compressive strength.The results indicates that the couplers with big swing angle must have the function of alignment reposition,and the couplers and he longitudinal compressive strength can influences the wheel flange wear of the locomotives remarkably.更多还原
