摘要
针对大功率腔体滤波器螺旋振子刚度小,在载机环境条件下特性响应曲线不稳定的问题,提出了一种螺旋振子的抗冲振创新设计思路与方法。通过铝材铣制成梯形截面螺旋振子增加其刚度,采用对称局部环抱的异形结构件对悬臂螺旋振子进行加固以提高抗冲振能力。优化设计后的振子顺利通过载机环境试验考核和电性能指标测试。该设计方案已成功应用于大功率跳频滤波器设备中,效果良好。
The rigidity of helix resonator of high - power cavity filter is low and the characteristic response curve is unstable in the environmental condition of carrier aircraft. To solve the problems, this paper introduces a novel measure to improve the impact and vibration resistance capability. Aluminum milling trapezoidal section and special - shaped symmetrical structure is used to reinforce the cantilevered helix resonator in order to enhance the resistance of impact and vibration. The helix resonator optimized has passed the check of environmental test in the carrier aircraft and electrical properties. The design has been successfully applied in high - power frequen- cy hopping filter and a good effect is obtained.
