摘要
为了快速实现船用螺旋桨有限元建模,为极限强度分析和疲劳校核做准备,针对船用螺旋桨的结构特点,利用MSC.Patran前后处理器的二次开发技术,开发了1套螺旋桨自动化建模软件,定义了螺旋桨建模的型值表标准格式,实现了螺旋桨几何建模和网格划分的自动化。对某冰区加强螺旋桨进行了建模和计算,结果表明,系统建立的螺旋桨模型能保持良好的光顺效果和网格质量,满足计算要求。本文提出了基于MSC.Patran的螺旋桨自动建模方法,避免了传统手工建模中复杂和重复的工作,大幅提高了螺旋桨设计分析效率,具有重要的参考价值。
In order to achieve finite element modeling of marine propellers quickly,and prepare for strength analysis and fatigue assessment,according to the structural feature of marine propellers,an automatic modeling software for propllers is developed based on MSC.Patran pre-postprocessor.The system defines the standardization of ship offset table and realizes automatic geometrical modeling and automatic meshing for propellers.After modeling and calculating the ice-strengthening propeller,the results show that the created model can keep good fairing effect and high quality mesh and meet the requirements of calculating.The paper puts forward a method for automatic modeling of propeller based on MSC.Patran,which can avoid a large number of complex and repetitive work in the traditional manual modeling process and substantially increase the efficiency of the propeller design and analysis and works with important reference value.
