摘要
压裂车作业时,车载设备传动系统存在明显的扭转振动现象。结合3000型压裂车车载设备传动系统,利用Pro/E软件建立其主要部件的三维模型,导入动力学仿真分析软件ADAMS进行分析。在特定挡位下,通过设置不同发动机转速,分析了传动系统扭转振动的情况。利用最小二乘法拟合传动轴共振频率和发动机转速的函数,对比压裂泵4挡工作频率,得出发动机转速为431r/min时,传动轴共振频率与压裂泵工作频率重合。
Transmission system of fracturing truck’s mobile unit torsional vibration obviously ap-peared when fracturing truck operating.In this paper,3D model was set up in Pro/E according to the transmission system for fracturing truck’s mobile unit,and then been imported in dynamic simulation analysis software ADAMS.Under the specific gear,torsional vibration of transmission system was analyzed by setting different engine speed.Using the least squares to fit the transmis-sion shaft resonance frequency and the function of engine speed and comparing the fracturing pump fourth gear working frequency,it is concluded that transmission shaft resonance frequenc y and fracturing pump working frequency overlapped when the engine speed was 431 r/min.
