船闸蘑菇头和帽接触有限元计算与优化

Finite Element Calculation and Optimization of the Contact Stress between the Mushroom Head and Cap of the Ship Gate

利用ANSYS软件计算船闸底枢蘑菇头和帽在均布外载作用下的接触应力、应变分布,分析表明:增加外载作用面积、改变接触面粗糙度对接触变形参数影响不大,增大球面半径、减小配合间隙、使用浮箱减小外载和注油孔偏移帽轴线都可有效降低接触应力以减少转动磨损。

By using software ANSYS this paper calculates the contact stress and strain distribution within the mushroom head and the cap uniformly loaded in the bottom hinge of the ship gate. The effect of loaded area, friction coefficient, ball radius and matching gap on contact deformation were studied. The calculated data show that increasing the contact area between the pair is the most effective measure of decreasing the contact stress. This paper supplies the optimal design of part structure with data.
