摘要

针对当前大型钻井垂直调整技术有限的状况,设计了一种适用于垂直钻井条件下的12输入6自由度并联调整装备。该装备机构具有6个结构对称的冗余支链,每个支链由复合转动副和复合球副组成,复合转动副与复合球副间通过两个移动副连接。基于ANSYS软件对机构进行模态分析,得到动平台前6阶频率分布和模态振型,以及动平台沿着X、Y、Z方向的位移频响。结果表明,动平台对46Hz频率的外力最为敏感。此外,采用三维搜索法确定了6自由度平台的工作空间,对分析参数对整个机构的影响关系及优化参数具有借鉴意义。

Abstract

Focusing on the current limited vertical adjustment technique of large-scale drillings,a 6-DOF parallel adjustment equipment with 12 inputs is designed for the working condition of vertical drilling.The equipment mechanism consists of 6branched chains with redundancy which are symmetrical in structure.Each of the chains is composed by a compound of rotate joint and a compound of spherical joint,while the two pairs are connected by two prismatic pairs.The modal analysis is carried out on the body which is based on ANSYS software,first six order frequency distribution and modal vibration mode,and along the X、Y、Zdirection of the displacement frequency response about the moving platform are got.The analysis consequence shows that the most sensitive of external forces to the moving platform is 46 Hz frequency.Otherwise,the working space of the 6-DOF platform is obtained by using the 3-D searching algorithm.The results have significant meanings in the further research on the correlation between the parameters and the whole mechanism,as well as the optimization of the parameter.
