摘要

为提高螺旋钻采煤机螺旋钻杆的强度和寿命,减轻钻杆重量,以螺旋钻采煤机的螺旋钻杆为研究对象,在满足强度要求的前提下,以钻杆重量最轻为优化目标,通过Pro/E建立实体优化模型,采用有限元法,在Ansys Workbench软件中进行有限元强度分析,通过观察应力云图,选择螺旋钻杆的壁厚、叶片厚度、高度和螺旋角为变量,对钻杆结构进行参数优化,结果表明,螺旋钻采煤机螺旋钻杆的强度得到了明显提高,应力减小了15.8%,重量减轻了6.4%,延长了钻杆的使用寿命。

Abstract

In order to improve the strength and life of the spiral drilling machine,and reduce the weight of the drill pipe,it took the spiral drill pipe of the spiral drilling machine as the research object. On the condition of meeting the strength requirement,it selected the weight of the drill pipe to be the lightest as the optimization goal. The solid optimization model was established in the software of Pro/E. The strength analysis was proceeded in the software of ANSYS Workbench based on finite element method,as the result it selected the thickness of the drill pipe and blade,height,helix angle as the optimizing parameters by observing the stress nephogram to optimize the structure parameters of the drill pipe. The result indicates that the strength of the spiral drilling machine has improved obviously,the stress is reduced by 15. 8% and the weight is reduced by6. 4%. The life of the drill pipe has been extended.
