摘要
对两圆柱体接触问题和平面接触问题进行分析,探讨了接触区应力的收敛性.对某枞树形圆弧齿榫接结构的接触区应力进行了数值计算和分析.利用有限元软件ANSYS进行了接触分析,对比了梯形齿和圆弧齿榫接结构的应力结果,并采用光弹实验进行了验证.研究结果认为,与梯形齿榫接结构相比,圆弧齿榫接结构使接触应力、第三主应力和等效应力等降低.在此基础上,对圆弧齿榫接结构进行了优化分析,通过优化进一步降低了榫接结构的应力水平.
Two cylinders contact problem and plan contact problem were analyzed, and feature of convergence was discussed. Some numerical calculations of an arc tooth tenon joint with three teeth were done. Then, the contact stress with ANSYS was analyzed, and the results of trapezoid tooth and arc tooth tenon joint were compared to find that the latter decreased the contact stress, the third principle stress and von Mises stress. Based on this, some optimizations about the arc tooth tenon joint were done, and the stress was decreased again by optimization.
