摘　　要：在研究轮胎 /路面静态接触问题中 ,采用了直接将接触面间约束条件作为边界条件施加到系统中的求解方法 .该方法避免了应用传统的 Lagrangian乘子法引起的系统变量数的增加 ,同时也避免了由于罚函数法中罚数选取不当给系统数值的稳定性造成的影响 .数值分析表明 ,该方法能够准确有效地对轮胎Due to the complexity of contact problem of tire/road interface, a direct approach was employed to apply the contact constraints and solve the contact problem during the study on the static contact problem of tire/road. The application of the direct approach avoids not only the increment of the variables compared with Lagrangian method but also the influence on the numerical stability because of the unsuitable penalty number when penalty function method is applied to the contact problem. The numerical example shows the validipy and effectiveness in the analysis of the contact problem of tire/road interface by this approach.
