可控震源重锤活塞杆动态行为规律与扰动控制研究
Study on vibroseis reaction mass-piston rod dynamic behavior law and disturbance control
摘要
Abstract
In view of vibroseis vibrator's key problems of big disturbance and low signal-to-noise ratio in the engineering application and combined with reaction mass movement path tests ,the dynamic behavior law of the reaction mass-piston rod was studied through theoretical calculation and numerical simulation .On this basis ,vibrator disturbance control was studied and the vertical passageway vibrator was put forward .Then the simulation results were compared with the results of horizontal passageway ,and the vertical passageway vibrator disturbance test verification was carried out .The results showed that the reaction mass was driven by the rotation torque around z axis and the piston rod was deformed ,which resulted in a point movement path of the reaction mass being a space curve and increased the vibrator disturbance .Therefore ,the key reason of large vibrator disturbance was the horizontal passageway .In addition ,the rotation torque did not influence the reaction mass and the piston rod deformation was improved greatly in the vertical passageway , which could reduce the vibrator disturbance effectively . Consequently , it is suggested that adopting the vertical passageway in the design of vibrator ,which is good for im-proving output signal quality and enhancing output signal resolution .关键词
