摘　　要：基于APDL参数化设计语言开发了多级离心泵泵轴强度计算程序,通过调入自编模型程序的脚本文件,执行SOLVE命令进行计算,实现了零流量工况和设计点工况下泵轴的参数化自动建模、载荷施加与求解以及计算结果的三维参数化显示,清晰描述了泵轴在不同工况下不同截面上的应力分布情况及危险点位置,完成泵轴强度的精确计算。应用实例表明,设计的应用程序计算准确、操作简单,计算结果直观形象,大大提高了泵轴强度计算效率,减少了分析成本。In order to avoid the disadvantages of cumbersome,error-prone,long cycle of shaft strength calculation by traditional method,a multi-stage centrifugal pump shaft strength calculation program was developed based on parametric design language APDL.By transferring script file of the self model program and executing the command SOLVE to calculate,parametric automatic modeling,load application and solution,and the results of 3-D parametric display under zero-flow conditions and design point conditions were realized.The stress distribution of the shaft at different conditions on different sections and dangerous position were clearly described,and the accurate calculation of the shaft strength can be performed.Application examples showed that the design and development application program was used friendly and can get accurate calculations with visual results.This program of shaft strength calculation greatly improved the computational efficiency of shaft strength and reduced the analysis cost.
