本文对五九式坦克履带板联接臂断裂原因进行了分析与计算,并提出相应的改进方案。应用“SAP5线性静动力结构分程序”的三维实体有限单元对履带板联接臂处迸行静力计算表明,将原履带板“反装”使前进时牵引力造成的最大有效应力由20公斤/毫米~2降到3公厅/毫米~2。进方案使最大有效应力由垫支时的32公斤/毫米~2降到倒车时的19公斤/毫米~2。因而,采用反装和改进的结构方案将会提高履带板的寿命。
This article analyzes and calculates the fracture reason of the joint arm of the five-nine tank track shoe, and puts forward the corresponding improvement plan. The static calculation of the joint arm of track shoe using “3D finite element of SAP5 linear static structure subroutine program” shows that the maximum effective stress caused by the original crawler plate “reverse loading” makes the traction force of forward track increase from 20 kg / mm ~ 2 down to 3 / mm ~ 2. Into the program so that the maximum effective stress from the support of 32 kg / mm ~ 2 down to 19 kg / mm ~ 2. Therefore, the use of reverse assembly and improved structural solutions will increase the life of the track shoe.
