摘要
随着车轮驱动式电动汽车的重量分配及车身构型的变化,其整体的动态性能将会产生较大的变化。针对此问题,开展适合于车轮式马达驱动的特殊悬挂与振动检测平台的研发,对于加速我国电动车的发展,推动我国机动车工业的发展,推进我国机动车行业的转型与发展,有着十分重大的现实意义。在此基础上,提出了一种新型的基于电子技术的轮轴传动式电动车悬挂实验平台。本文针对轮毂驱动电动汽车悬架振动问题,设计了一种试验台。该试验台具有可调节的支撑点高度和角度,能够模拟不同路面状态下的悬架振动情况。通过试验台的测试,可以评估悬架系统的性能,并进一步优化设计。此外,该试验台还可为相关研究提供数据支持,为轮毂驱动电动汽车的发展提供技术支持。本文针对轮毂驱动电动汽车悬架振动问题,设计了一种试验台。该试验台具有可调节的支撑点高度和角度,能够模拟不同路面状态下的悬架振动情况。通过试验台的测试,可以评估悬架系统的性能,并进一步优化设计。此外,该试验台还可为相关研究提供数据支持,为轮毂驱动电动汽车的发展提供技术支持。
