| 摘 要： | 为研究偏心引发的角振动与线振动耦合对弹性支撑惯导系统的影响，首先建立了振动耦合系统微分方程，然后采用通用有限元分析软件进行模态和随机响应分析计算。确立系统的动力学振动特性，从理论和数值计算两方面解释了角振动产生并与线振动耦合的原因——系统偏心。最后通过对具有不同偏心数值的多种仿真模型的分析计算．给出了偏心对系统的影响规律。

| Abstract: | To study eccentric inertia navigation system's coupling vibration, differential equation of coupling vibration system was built firstly, and then the modal analysis and the random response analysis were done using general FEM software-ANSYS to study the system's dynamic characteristic. Both explained the eccentric bring angel vibration. Finally, several FEM models with different eccentric were built to make clear the vibration effect of eccentric on inertia navigation system. |
