摘　　要：为了解决连续管注入头在运行中的振动问题,以某型号在用连续油管注入头集成装置为研究对象,通过有限元模态分析的方法对注入头的振动特性进行研究。研究表明,引发连续管注入头共振的主要因素为液压马达的振动,当液压马达转速为600~1 800 r/min时,连续管注入头在X向易引起共振,振动幅值为2.6 mm,与实际工况相吻合。通过该文研究可知,在实际工作中如果出现由于注入头共振导致的振幅过大和异响等问题,可以通过控制液压马达的转速或提升注入头的固有频率来降低箱体的振动。In order to study the vibration characteristics of the continuous tubing injection head and solve the vibration problem of the device in operation,the vibration characteristics of the injection head are studied through the finite element mode analysis on the integrated device of a continuous tubing injection head of a certain model.The results show that the main factor causing resonance of the continuous pipe injection head is vibration of the hydraulic motor;when the speed of the hydraulic motor is 600~1 800 r/min,it is easy to cause resonance in the X direction,and the vibration amplitude is 2.6 mm,which is consistent with the actual working conditions.In practical work,to avoid problems such as excessive amplitude and abnormal noise caused by the resonance of the injection head,the speed of the hydraulic motor can be controlled or the natural frequency of the injection head can be increased to reduce the vibration of the box.
