【摘要】：針對船用復(fù)合材料螺旋槳葉片,分別采用殼單元賦予不同截面參數(shù)和實體單元賦予不同等效材料參數(shù)兩種建模方法進行了有限元分析,對比了殼單元和實體單元模型的模態(tài)、均布壓力載荷下的響應(yīng)以及均勻溫度場中的熱變形。結(jié)果表明:對于從槳根到槳尖各位置鋪層不同的葉片來說,兩種建模方法在建模時間和鋪層調(diào)整便捷性方面各有利弊;模態(tài)分析中兩種模型的固有頻率和振型計算結(jié)果存在一定差異,它們均可在一定條件下用于復(fù)合材料螺旋槳葉片模態(tài)計算;兩種模型中,模擬均布壓力載荷下的響應(yīng)時應(yīng)采用殼單元模型,而分析葉片在均勻溫度場中結(jié)構(gòu)的熱變形應(yīng)采用實體單元模型。
[Abstract]:In this paper, the finite element analysis of ship composite propeller blades is carried out by using two modeling methods: shell element with different cross-section parameters and solid element with different equivalent material parameters, and the modes of shell element and solid element model are compared. Response under uniform pressure and thermal deformation in uniform temperature field. The results show that the two modeling methods have their advantages and disadvantages in modeling time and ease of layering adjustment for blades with different layers from the propeller root to the tip of the propeller. In modal analysis, the natural frequencies and modes of the two models are different, and they can be used in the modal calculation of composite propeller blades under certain conditions. The shell element model should be used to simulate the response under uniform pressure and the solid element model should be used to analyze the thermal deformation of the blade in the uniform temperature field.
