针对液压上卡盘在钻探过程中受力变形复杂的问题,为了更好的评估液压上卡盘在工作时内部的变形情况,利用CATIA软件的机械设计模块和有限元分析模块,建立JU-1000型钻机液压上卡盘的三维模型,同时模拟上卡盘内部碟形弹簧组件的结构强度。通过分析碟形弹簧组件的应力与应变,得出JU-1000型钻机碟形弹簧组件的最大应力值控制在材料的许可应力范围内,能够满足钻机对液压上卡盘的工作需求,同时论证了产品设计的合理性。
In order to evaluate the internal deformation of the hydraulic upper chuck during operation, aiming at the problem that the hydraulic upper chuck undergoes complicated deformation and deformation during drilling, a mechanical design module and a finite element analysis module of CATIA software are used to establish the JU-1000 Type drilling rig hydraulic three-dimensional model of the chuck, while simulating the upper chuck internal disc spring structural strength components. By analyzing the stress and strain of the disc spring assembly, it is concluded that the maximum stress value of the disc spring assembly of JU-1000 is controlled within the allowable stress range of the material to meet the working requirements of the hydraulic chuck on the rig. Meanwhile, The rationality of product design.
