摘　　要：作战舰船在海面执行任务期间,舰载惯性导航系统工作环境恶劣,为保证其导航精度,有必要安装隔振缓冲装置。本文以八杆并联缓冲平台为研究对象,根据矢量积法推导出雅克比矩阵,建立了广义固有频率数学模型,分析结构参数对系统固有频率的影响,并借助ADAMS软件进行验证。结果表明,所建广义固有频率数学模型正确,分析所得结果为类似多杆并联缓冲平台的优化设计提供理论指导。During the operation of combat ships on the sea surface,the working environment of the shipboard inertial navigation system is harsh,in order to ensure its navigation accuracy,it is necessary to install vibration isolation and buffer devices.This paper took the eight-bar parallel buffer platform as the research object,derived the Jacobian matrix according to the vector product method,established a generalized natural frequency mathematical model,analyzed the influence of structural parameters on the natural frequency of the system,and verified it with the aid of ADAMS software.The results show that the mathematical model of the generalized natural frequency is correct,and the analysis results provide theoretical guidance for the optimization design of similar multi-pole parallel buffer platforms.
