| 摘 要： | 应用双边接触模型推导出了求解刚架弯扭接触的有限元混合变量矩阵方程。基于此算法，研制了可以在微机上运行的自卸式挂车强度分析的应用程序。给出的算例理论值与有限元值相吻合，以国产自卸式挂车为例，得出了挂车车架和车厢架的接触反力及应力分布规律

| Abstract: | The equation of mixed matrix of finite element for contact of rigid frames is obtained by using the double sides contact model. Based upon this, an applied program is compiled. Strength of the agricultural dump trailer is overally and correctly analyzed with it. The results calculated by the program are well coordinated with theoretical one. At last, the contact forces and stresses of the trailer are given in this paper. |
