不同腔角和腔深的阶梯腔尾轴承有限元力学性能研究

建立水润滑动静压阶梯腔尾轴承的三维实体模型,并将建好的模型导入到AnsysWorkbench软件中进行有限元静力分析.主要研究不同腔角和腔深对船舶尾轴承力学性能的影响,结果表明:对比3种腔角的尾轴承应力、应变和位移情况发现,当腔角是20°时,尾轴承的力学性能最优;合适的腔角比例能有效的改善尾轴承的力学性能,当深浅腔的腔角比例是1:4时,此时力学性能最佳;尾轴承两腔的腔深差距不能过大,保持过渡平缓,当深腔腔深为1.6mm,浅腔腔深为1mm时,轴承的力学性能最优.

Finite element mechanics performance study on different angle and cavity deep the ladder cavity stern bearing

Establish water lubrication ladder of dynamic and static pressure cavity stem bearing three-dimensional entity model,and import the model into the finite element static analysis in ANSYS Workbench software.Mainly studied the different Angle and cavity depth on the mechanical properties of ship stern bearing,The results show that the stern bearing mechanical properties is best when the Angle of cavity is 20,Comparing three kinds of chamber Angle of stern bearing stress,strain and displacement situation;Appropriate proportion of chamber Angle can effectively improve the mechanical properties of the stern bearing.the stern bearing mechanical properties is best,when the Angle of cavity of the cavity depth proportion is 1:4;Stern bearing cavity of the deep gap do not become too big,when the deep cavity is 1.6 mm,shallow cavity is 1 mm,the stern beating mechanical properties is best.
