摘要

本项目工作涉及船舶螺旋桨叶片强度的建模和分析。螺旋桨是一个复杂的几何形状，需要高端的建模软件。利用Solidwork 2014和Matlab R12开发了螺旋桨的实体模型。使用Ansys对模型进行网格划分。在ANSYS 14.5软件中对复合叶片螺旋桨进行静、动分析。得到的应力完全在材料各向异性的极限之内。确定了复合叶片螺旋桨的挠度。采用田口法求最优解。利用旋翼动力学方法确定了螺旋桨的临界转速。对比表明，通过改变轴速、螺旋桨水压力等参数，可以找到螺旋桨设计的最佳方案。

Static and Rrotordynamic Analysis of Composite Blade Marine Propeller

This project work deals with modelling and analysing the propeller blade of a marine vehicle for their strength. A propeller is a complex geometry which requires high end modelling software. The solid model of propeller is developed by using Solidwork 2014 & Matlab R12.The meshing is generated for the model using Ansys. Static and rotordynamic analysis of composite blade propeller is carried out in ANSYS 14.5 software. The stresses obtained are well within the limit of anisotropic property of the materials. The deflection for composite blade propeller is determined. Optimal solution was found by using TAGUCHI method. The critical speed of the propeller is determined using rotordynamic. On comparison which shows that by changing different parameters like speed of shaft and pressure of water on propeller we found optimum solution for the design of propeller.
