摘要
本文运用有限元方法分析惯性制导平台台体的刚度和强度，通过模型离散，模拟实际施加外力，计算得到模型的位移场和应力场，获得了安装面的转角位移及应力极值等关心的物理量，并通过动力分析程序得到了结构各阶固有频率和振型。
In this paper the rigidity and strength of the inertial navigation plat-form are analysed by the Finite Element Method(FE).The structure is simulated bya discrete model and the elemerit body forces are converted to the corresponding nodalforces. The global displacement and stress fields of several load cases are compared.The concerned values of angular dispiacements of the assembling plane and the maximum of the stress are derived. Eight natural frequencies and modes are computed bythe dynamic analysis program using the same model.
