| 摘 要： | 提出了一种新颖的以马达和油缸双驱动车辆急加速的驱动方式。以某国产连续式捣固车工作小车行走为例,分析了此加速方式的工作原理、主要性能和可能存在的局限性。针对在运行中作业小车驱动马达频繁断轴的现象,进行系统的综合分析和计算,并建立了AMESim仿真模型以对马达轴所受扭矩进行仿真。结果表明:在缩短油缸的作用时间和在油缸入口增加阻尼孔的作用下,有效地防止了马达的启动冲击和功率寄生,在一定程度上提高了马达的寿命,并使此驱动方式的性能得到优化。

| Abstract: | A new kind mode of double drive which motor and cylinder drive together vehicle to snap-acceleration is proposed.Taking a satellite of the domestic continual tamper with the drive mode as a example,some analyses are made,including working principle,main performance and possible limitation.On the basis of phenomenon that the satellite's drive motor fault axle frequently at wheeling,the paper made a overall analyzing and calculating and emulated the torque of motor axle bearing by AMESim models.The results in... |
