摘　　要：文章通过理论计算分析,可得出隧道清洗车水罐内部液态水晃动的固有频率及振型;通过ANSYS分析软件对水罐及内部液态水进行有限元仿真分析,得到水罐内部液态水晃动的固有频率及振型;对比两者结果,误差在有效范围内,理论计算结果正确;结合理论计算与有限元仿真分析结果建立水罐的等效力学模型,用于隧道清洗车的动力学仿真分析。Through theoretical calculation and analysis of natural frequency and vibration mode of the tunnel cleaning vehicle tank internal liquid water sloshing;analysis software for finite element analysis of internal tank and liquid water by ANSYS, we got the natural frequencies and vibration modes of internal tank sloshing of liquid water;than the two results,the error in the effective range,theory the calculation results were correct;according to the theoretical calculation and finite element simulation of the equivalent mechanical model was established for water analysis, dynamic simulation analysis of tunnel cleaning vehicle.
