Vibration Isolation Design and Bracket Topology Optimization for UAV Inertial Navigation System

  • 摘要: 支架作为惯导减振系统的重要组成部分,其动态特性对惯导减振系统的影响不可忽视。以某型号无人机惯导减振系统为例,根据其动态特性要求,对该系统的减振器参数进行了设计与工艺匹配;其次,基于变密度法对支架进行了拓扑优化,质量减少了19.9%,系统的一阶固有频率由57.09 Hz提高到58.76 Hz。最后,分别进行了惯导减振系统线振动和角振动实验,实验结果表明:优化后惯导减振系统的谐振频率为55 Hz,最大加速度传递率为2.2,-3 dB带宽在30~40 Hz范围内,相位滞后在5.16°~9.17°内,均满足设计要求。说明该惯导减振系统的设计及其支架拓扑优化方法是有效的。
