摘要
应用双边接触模型推导出了求解开口薄壁杆弯扭接触的有限元混合变量矩阵方程。基于此算法，编制了有限元程序。应用该程序对农用自卸式挂车进行了强度分析计算，并用实验给予了验证。
The equation of mixed matrix of finte elemen for contact of open thin wall beamswas obtained by using the double. sides contact model.Based upon this,the program ofthin wall beams contcat was developed.The agricuItural dump trailer was computed ana-lyticlly by using this program,and the program was well tested by the experiments.
