穿梭油船货油泵电机基座的强度分析与模态分析

基于有限元法,对某穿梭油船货油泵电机基座进行多工况强度分析与模态分析,计算其固有频率,并对比主机、螺旋桨等激励源频率,分析共振可能性.在分析过程中采用点质量方式简化电机质量,以壳单元代替基座实体模型,通过DesignModeler软件建立模型、划分网格和约束边界条件,显示应力和变形计算结果,对设计方案的评定和优化具有较...

Strength Analysis and Modal Analysis of Cargo Oil Pump Motor Base for Shuttle Tanker

Based on the finite element method,the strength analysis and modal analysis of cargo oil pump motor base for a shuttle tanker under multiple working conditions are made.Its natural frequency is calculated,and the resonance possibility is analyzed by comparing the frequencies of main engine,propeller and other excitation sources.During the analysis,the point mass method is used to simplify the motor mass,the shell element is used to replace the solid base model,and the DesignModeler software is used to establish the model,divide the grid,and constrain the boundary conditions,and display the calculation results of stress and deformation,which is of a better guiding role in the evaluation and optimization of the design scheme.
