| 摘 要： | 车辆冲击振动常发生于3个方向,兼有移动和转动,故车辆需要多维隔振.如将现有一维隔振技术直接应用于多维隔振,则隔振装置需要多层结构组合,非常复杂,且容易干涉.为此,提出用2个6自由度特殊布置的Stewart机构和上下平台组成车辆用多维隔振装置,利用一层结构实现多维隔振.ADAMS仿真表明,在下平台施加脉冲激励时,上平台移动与转动6个加速度明显小于下平台相应数值,且均随时间迅速衰减.仿真计算了脉宽、阻尼以及弹簧刚度等参数对隔振效果的影响.

| Abstract: | The impact and vibration of vehicles often occurs in three directions along or around axes,which need multidimensional vibration isolation.If the technology was applied on one dimensional vibration isolation into multidimensional vibration isolation simply,the vibration isolation device would interfere.So a multidimensional vibration isolation device of vehicles was developed.It is composed of two Stewart mechanisms: down platform and up platform.The two Stewart mechanisms with six degrees of freedom lead t... |
