本文采用一种特殊单元——六节点等参接触元研究平面接触问题的有限元解法。文中推导了该单元的有限元公式,用FORTRAN语言编制了相应的程序。作为数值计算的实例,文末计算了解放牌汽车前桥迭板弹簧的应力与变形,并对计算结果作了分析和讨论。 In this paper, a special element - a six-node isoparametric contact element is used to study the finite element method of planar contact problem. In this paper, the finite element formula of the unit is deduced, and the corresponding program is compiled by FORTRAN language. As an example of numerical calculation, the stress and deformation of the pallet spring at the front axle of Jiefangpai Automobile are calculated and the results are analyzed and discussed.
