掘进机的截割头头体部分与花键套之间采用焊接方式联接,焊缝部位承受较大的应力,是截割头的薄弱环节。采用SolidWorks Cosmos Works有限元方法对其进行静态分析,校核焊缝强度并进行了疲劳寿命分析。
Cutting machine cutting head body part and the spline sleeve between the welding connection, the weld site to withstand greater stress, the cutting head is the weak link. SolidWorks Cosmos Works finite element method was used to analyze the static analysis of weld strength and fatigue life analysis.
