摘要
本文基于二维平面弹性问题的基本方程推导出边界积分方程，然后采用二次等参插值建立了边界元方程和数值分析程序。并采取了若干有效措施，克服了边界元法在连杆受力分析中存在的一些困难。对１０２柴油机连杆的小头部分进行了数值计算，结果表明二次等参边界无法用于柴油机连杆的应力分析是有效的。
A boundary integral equation for two dimension elastostatic problem is derived by means of weighted residual method. After discretizing,the formula of the isoparametric quadratic boundary element method is presented. Some aspects in analysis of connecting rod with BEM are discussed. The program developed is used to analyse the stress of connecting rod in 102 type diesel engine. The work of this paper shows that more satisfactory result can be yielded by using isoparametric quadratic BEM.
