摘要

为有效控制、减弱旋挖钻机钻杆振动，基于吸振原理设计旋挖钻机钻杆减振器；据钻杆振动特点建立钻杆-减振器系统动力学模型，并仿真验证减振器减振效果；建立旋挖钻机钻杆减振系统对减振器减振效果进行试验研究。结果表明，钻杆安装减振器后振幅明显降低，减振作用显著。

Abstract

In order to control and reduce the drillstring vibration more effectively for rotary drilling rig, a drillstring absorber was designed based on vibration absorption principle. According to the vibration chatacteristics of drillstring, dynamic model of drillstring with the absorber was established and its effect of suppressing vibration was proved with simalation. Then, the suppressing vibration test system was set up to verify the effect of the drillstring absorber. The results show that the vibration suppression of drillstring is reduced obviously after the installation of the drillstring absorber, and the drillstring absorber has better vibration damping effect. The research will offer a reference in reducing vibration for other engineering machinery manufactures.
