摘　　要：针对某机载雷达频综器优良隔振性能要求提出相应的隔振系统设计方法。文中对该频综器在静态和宽带随机振动下的相噪进行了理论分析与仿真,并结合频综器所处的恶劣环境和苛刻的体积要求,利用隔振理论分别提出基于丁基橡胶的晶振模块和其他敏感模块的二级隔振系统设计以及整机去耦、去谐、提高总体刚度的工程实现方法。测试结果表明,对某机载频综器隔振系统的研究及对其采取的隔振措施是行之有效的,整机指标完全满足实际需要。Aiming at the excellent vibration isolation of an airborne radar frequency synthesizer, the article puts forward relevant design method of the vibration isolation system. It analyses and simulates the phase noise of the frequency synthesizer in environment of static state and wideband random vibration, with condition of the bad environment and the special demand of volume, using the vibration isolation theory to put forward the vibration isolation system of the crystal oscillator module and the other sensitive module based on butyl rubber, and also the project implement of decoupling, detuning, enhancing stiffness in the whole system. The test result indicates that the study on vibration isolation system of the frequency synthesizer and measures taken to prevent the vibration are effective, and all indexes meet actual demands.
