基于有限元法不同型腔结构艉轴承的力学性能分析

Mechanical Properties of Different Stern Bearing Cavity Structures Based on FEM Analysis

型腔结构能改善艉轴承的承载能力和工作环境,并且影响艉轴承的力学性能。利用有限元法,研究了三种不同型腔结构以及不同腔深的长方形腔艉轴承的静力学性能。结果表明:长方形腔的力学性能最优;浅腔相对于深腔性能更好。

Cavity structure can improve the bearing capacity and the working environment of stern bearing and can influence the mechanical properties of the bearing. The finite element method is used to study the static mechanical properties of three different cavity structures and the static mechanical properties of rectangular cavity stern bearing with different chambers depths. The results show that the mechanical properties of the rectangular cavity are best and the performance of shallow cavity is better than the petformance of deep cavity.
