摘要
预应力索-杆张力结构雷达阵面是一个包含索-杆张力结构%预应力在内的一种新型的阵面结构形式&为此,建立了预应力索-杆张力结构雷达模态数值计算模型,对“降温法”施加预应力进行了分析和验证,进而对该新型雷达阵面结构模态进行了数值分析,得到了某预应力下该型雷达阵面前十阶固有振动频率及其相应固有振型,并对预应力大小对该新型雷达阵面的自振频率的影响进行了分析.结果表明,预应力对阵面的刚度影响明显.
Prestressed csble-rod tension structure phased array radac antenna array it a new type of structure includes csbO-rod tension structure and prestressed structure.The prestressed cable-rod tension structure radac modal numerical model was established,and the method of applying prestress by ccoling was analyzed and validated.The numerical analysis of the new radae array structure modal was ccrried our Accordingly,the first ten ordee natural vibeation frequencies and itr correspondingnatural vibeation modes of thefinite element model of thepeestressed cable-rod tension structure phased array radae antenna array were determined.The effects of prestress on the natural frequency of vibration of the new radae array was analyzed.The resultr showed that prestress had a significant onfeuenceon&hefeon&aesofnessseucuee.
