【摘要】：編織復合材料因其高強度、高模量等良好力學性能而被廣泛應用于羽毛球拍的制造生產(chǎn)中。其中,碳纖維編織復合材料制造的球拍具有韌性好、質(zhì)量輕、擊球速度快等特點�，F(xiàn)階段關(guān)于羽毛球拍等體育用品的設計,僅僅是依據(jù)經(jīng)驗和大量的實驗來完成而缺少對其力學性能的理論分析與計算。另外,由于研究方法的限制,關(guān)于復合材料的研究大都集中在一個具有代表性的單胞模型上,而對于編織復合材料整體構(gòu)件的研究卻非常之少。因此,對編織復合材料羽毛球拍整體構(gòu)件進行有限元參數(shù)化建模和數(shù)值模擬分析顯得尤為重要。本文以羽毛球拍為研究對象,首先采用ANSYS軟件分別建立了二維二軸和二維三軸兩種編織形式的復合材料羽毛球拍有限元參數(shù)化模型,其中包括基質(zhì)相和纖維相兩相模型;其次對兩種編織形式的羽毛球拍模型進行整體力學分析、失效判別分析,為其結(jié)構(gòu)設計提供了理論依據(jù);然后選取拍桿部分為研究對象進行了彈性性能預測,結(jié)果顯示了有限元區(qū)域疊合法的可實施性;最后基于可視化編程軟件和有限元分析軟件開發(fā)了羽毛球拍尺寸設計及分析計算軟件,該軟件能夠完成對羽毛球球拍的參數(shù)化設計和有限元分析計算。
[Abstract]:Braided composites are widely used in the manufacture of badminton rackets due to their high mechanical properties such as high strength and high modulus. The racket made of carbon fiber braided composite has the characteristics of good toughness, light weight and fast batting speed. At present, the design of badminton racket and other sporting goods is only based on experience and a large number of experiments to complete the lack of theoretical analysis and calculation of its mechanical properties. In addition, due to the limitation of research methods, most of the research on composite materials is focused on a representative unit cell model, but the research on braided composite whole components is very little. Therefore, the finite element parametric modeling and numerical simulation of the integral components of the braided composite badminton racket are particularly important. In this paper, the badminton racket is taken as the research object. Firstly, the finite element parameterized model of two dimensional two axis and two dimensional three axis braided composite badminton racket is established by ANSYS software, which includes matrix phase and fiber phase two phase model. Secondly, the integral mechanics analysis and failure discriminant analysis of two kinds of badminton racket models are carried out, which provide the theoretical basis for the structure design. Then, the elastic performance is predicted by selecting the racket as the object of study, and the results show the feasibility of the finite element region stacking method. Finally, based on the visual programming software and finite element analysis software, the size design and analysis calculation software of badminton racket is developed. The software can complete the parametric design and finite element analysis calculation of badminton racket.
