The shock response spectrum was calculated based on the acceleration time-history measured in the shock environment by improved recursive formula and statistical estimate. Then, it was used to guide the parameters design of the shock isolation system. In order to verify the design result, transient dynamic analysis was proposed in ABAQUS. To simulate the shock environment, acceleration time-history was acquired through time-history waveform synthesis and it was used as the base motion in transient dynamic analysis. The result indicates that the shock suffered by the SINS with the designed shock isolation system was declined to an acceptable range, which means the designed shock isolation system was successful in the view of dynamics characteristics. It is significant for the engineering application of FOG SINS., authors=TANG Xiaqing, GAO Junqiang, WU Meng, ZHANG Huan, authorsList=TANG Xiaqing;GAO Junqiang;WU Meng;ZHANG Huan,

articleAbstract=针对环境冲击、振动会对光纤陀螺捷联惯导系统结构及测量精度造成不良影响,进行了隔冲系统的设计与分析。利用改进的递归数字滤波算法和统计估计技术,根据冲击环境下测量得到的加速度时程,计算了冲击响应谱图,用于指导隔冲系统参数设计。为验证设计结果,利用冲击响应谱合成技术得到模拟实际冲击环境的加速度时程;在有限元软件ABAQUS中,以该加速度时程为基础运动激励进行瞬态动力学分析。根据分析结果,设计的隔冲系统可以使捷联惯导系统承受的冲击作用降低到所能承受范围内,表明所设计的隔冲系统在动力学特性角度可满足使用要求。,
