摘　　要：利用ANSYS软件建立带式输送机角型传动滚筒头架有限元模型并进行模态分析,得出系统前10阶固有频率及振型,结果表明头架的立柱以及斜撑与中部横梁的接头处为可能破坏的区域,应避免受到频率接近固有频率的外部激励,并采用适当的减振措施。A finite element model of spandrel frame of belt conveyor driving drum is established and its mode is analyzed by ANSYS software.The first 10 steps natural frequency and the mode shapes of the system show that the spandrel frame＇s upright pillar,the connection between the middle crossbeam and the inclined pillar could be destroyed by vibration.The external excitation which is close to spandrel frame＇s natural frequency should be avoided.On the other side,the suitable antivibration measure is also needed.
