支架是滑索的主要受力零件之一,在绳索拉力作用下,易产生应力集中。利用Inventor软件对滑索支架进行建模、有限元分析等,旨在探讨其应力分布,并寻求优化的结构设计。分析结果显示,滑索支架在相同载荷条件下,随着支杆结构位置变化,最大应力集中值改变。横斜杆结构形态时,最大应力集中值只是横杆滑索支架的30%。另外,左右立支架与斜支撑架间的角度a的改变对于滑索支架的最大应力值有着明显影响。综上所述,在横斜杆状态下,横斜杆在30°±1°之间时,应力集中值最小。

the bracket is one of the main force parts of the slip rope, which can produce stress concentration under the action of rope. Using the Inventor software to model it, the finite element analysis is designed to explore its stress distribution and optimize the structure design. The analysis results show that the maximum stress concentration value of slip rope is changed under the same load condition with the position of the support rod. The maximum stress concentration is only 30% of the strut of rod slip. In addition, the change of Angle a between the left and right stand and the inclined support frame has obvious influence on the maximum stress value of the slip bracket. Given all this, in the condition of extremely stem, extremely rod between 30°+1°, minimum value of stress concentration.
