摘　　要：长距离、大运量、高速度、大功率成为带式输送机的发展趋势。速度的提高带来了一系列问题,输送带有可能与机架等支承装置发生共振。通过对几种型号的输送带进行模态分析,详细分析了输送带的固有频率,探讨了发生共振的可能性。Belt conveyor are marching on the direction with longer distance,larger power and higher speed.With the higher speed,conveyor belt and its bracer may produce sympathetic vibration.Through modal analysis of several type conveyors belt,this thesis detailedly analyses its inherence frequency and discusses the possibility of sympathetic vibration.

关 键 词：有限元 模态分析 模态响应 固有频率
