摘要
文中简要介绍了某高机动雷达天线单元及其举升机构,应用ADAMS软件对该雷达天线举升机构建立了虚拟样机模型,对天线在自动架设过程中的精确位置进行求解,并分别进行了不同工况的动力学仿真分析。最后得到驱动丝杠的轴向载荷及伺服电机的功率。天线的运动情况清晰直观,详细比较了不同工况下天线运动过程中的力学性能差异。仿真结果表明,虚拟样机技术为产品的系统动态性能分析提供了有效手段。该研究结果可为工程设计提供理论依据。
This paper briefly introduces a highly mobile radar antenna and its lifting mechanism. The virtual prototype model of the radar antenna lifting mechanism is established by ADAMS software. Also the exact displacement of the antenna in the process of antenna auto set-up is solved and the dynamics simulation analyses of different working conditions are performed. Finally both the axial load of driving lead screws and the power of servo motors are obtained. The movement of the antenna is clear and intuitive. The differences between the mechanical properties of antenna movement under different conditions are compared in detail. Simulation results show that virtual prototyping technology is an effective method for analyzing system dynamic properties.This study result can provide a theoretical basis for engineering design.
