摘　　要：本文以指导捷联惯组减振系统设计过程为目的,结合捷联惯性组合减振系统对角共振频率的特殊要求,分析对线、角振动共振频率关系,得出了理想情况下捷联惯性组合减振系统线、角共振频率的比例关系,总结归纳了常见惯组不同减振器布置方式的线、角共振频率的关系,给出了捷联惯组结构设计的一般原则。The present research was aimed to guide the design process of vibration reduction system of strapdown inertial unit. The relationship was analyzed between linear and torsional vibration resonance frequency according the requirement of torsional resonance frequency. The results showed a proportional relationship between liner and torsional vibration resonance frequency. Finally, the current study summarized the relationship between liner and torsional vibration resonance frequency in different shockstrapdown inertial system.
