摘　　要：设计一种新型车载机动雷达天线举升机构,采用缸筒一体集成设计,有效实现机构的小型化及轻量化。驱动及传动采用伺服电机、减速机构及机械式二级同步滚珠丝杠的组合形式。进一步对举升机构的载荷及精度进行分析。根据NX仿真及试验,验证了所提出举升机构的高精度、高刚度及高强度技术特征。This paper proposes a new type of antenna lifting mechanism for mobile radar on vehicle,which adopts a cylinder barrel integrated design and can effectively achieve miniaturization and lightweight of the mechanism.And its drive and transmission employs the combination form of servo motor,reduction mechanism,and mechanical two-stage synchronous ball screw.The load and accuracy of the lifting mechanism is further analized.The NX simulation and experiments verify the high accuracy,high stiffness and high strength of the proposed lifting mechanism.
