某舰载雷达力学性能研究
摘要
雷达结构设计水平对于实现雷达系统电气性能有着重要的影响,某舰载警戒雷达系统结构复杂,使用条件恶劣,雷达结构工程师在设计工作中必须以规定的结构质量实现雷达系统的刚强度要求,确保在规定的工况下正常工作和不发生破坏,引入有限元和动力学的计算方法,在产品设计的各个阶段了解雷达结构的力学响应状况,为结构的设计提供指导和验证支持。
本文结合水动力软件AQWA,模拟舰船在不同海况下的运动情况,得到了其质心位移随时间的动态变化情况；建立了雷达的有限元模型,进行雷达系统和天线部件的模态分析计算,根据结构的各阶振型,找到了容易发生刚度不足的区域；计算了雷达系统在不同风载荷下的静态响应,验证了雷达反射面在这些载荷下结构刚强度能够满足设计指标要求,提出了进一步提高结构静态性能的方案；建立雷达系统的动力学模型,仿真计算了雷达系统在受舰船摇荡和自身旋转时结构的动态响应,为雷达天线和雷达座的设计提供了有益的参考。
The level of structural design of radar systems for the electrical performance of radar has an important effect. The work of structural engineers in the design of the structure muse be based on the quality of the provision of the stiffness and strength of radar system requirements normal operating conditions to ensure the required work and damage does not occur for the harsh conditions. The finite element method and dynamics of multibody systems method be introduced in various stages of product design to understand the mechanical response of radar structure of the situation and to provide guidance for the structural design and verification support.
In this paper, hydrodynamic software AQWA has been used to simulate the center of mass displacement over time of dynamic in different sea conditions. A finite element modal for radar system and antenna component modal are established and calculated. The area less prone to stiffness has been found according to the structure of the vibration modes. Calculation of the radar system at the strength and stiffness of these loads can meet the design requirement. Further improve the structure of the static properties of programs has been proposed. A radar system dynamics modal has been established and simulated the dynamic response of radar system by the shake of ship. This work will provided a useful reference for the radar antenna and radar-seat design.
