摘　　要：某型导弹起竖臂静动态有限元模型在ANSYS中建立,并采用动静法对其分析。模型含起升载荷,臂架结构自重载荷、导弹重力等载荷。当起竖臂所载起升质量突然离地起升或下降制动时,将起升和导弹重力载荷乘以起升载荷动荷系数或乘以起升冲击系数,获得前10阶振型。对起竖臂动态分析中,起竖臂低阶振型表现为起竖臂整体的振动,高阶振型则为起竖臂某个局部的振动。The finite element model of static-dynamic for certain missile erecting arm was built in ANSYS, and was analyzed in dynamic-static method. The model includes rising load, load of arm structure weight, load of missile weight and so on. When the erecting arm rose or stopped suddenly, the rising load and the load of missile weight were multiplied with the rising-load coefficient or rising-impulse coefficient; then, the first 10-vibration mode was got. In the dynamic analysis of rising arm, the lower vibration mode of the erecting arm was the vibration of the whole rising arm and the higher vibration mode of the erecting arm was the vibration of certain parts of the arm
