摘要
由于螺旋桨几何曲面复杂,为实现随边削边几何建模与振动分析功能,该文开发了一款通用的螺旋桨随边削边振动特性快速预报软件。采用有限元法、基于QT平台,结合MATLAB程序语言与ANSYS模块功能完成了螺旋桨随边削边振动分析软件的开发。基于该软件,对4383桨前五阶固有频率数值进行了求解与分析,结合参考文献数据发现相对误差均在5%以内,证明该软件程序和计算结果的正确性。该软件使用方便、运算快速,具有良好的工程应用价值,为实现螺旋桨随边削边后船-机-桨合适匹配提供了新的分析途径。
Owing to the complex geometric curved surface of the propeller,general software for the rapid prediction of the vibration characteristics of the propeller with trailing edge cutting is developed for the geometric modelling and vibration analysis of the trailing edge cutting.The development of the software for the vibration analysis of the propeller with trailing edge cutting is completed by using the finite element method together with the MATLAB programming language and the ANSYS module based on the QT platform.This software is used to calculate and analyze the first five-order natural frequency values of the 4384 propeller.It is found that the relative errors are within 5%combined with the published data in order to prove the accuracy of the software program and the calculation results.The software is characterized of easy usage,fast calculation and great engineering application value.It provides a new analysis method for the matching of ship-machine-propeller after the trailing edge cutting.
