【摘要】：编织复合材料因其高强度、高模量等良好力学性能而被广泛应用于羽毛球拍的制造生产中。其中,碳纤维编织复合材料制造的球拍具有韧性好、质量轻、击球速度快等特点。现阶段关于羽毛球拍等体育用品的设计,仅仅是依据经验和大量的实验来完成而缺少对其力学性能的理论分析与计算。另外,由于研究方法的限制,关于复合材料的研究大都集中在一个具有代表性的单胞模型上,而对于编织复合材料整体构件的研究却非常之少。因此,对编织复合材料羽毛球拍整体构件进行有限元参数化建模和数值模拟分析显得尤为重要。本文以羽毛球拍为研究对象,首先采用ANSYS软件分别建立了二维二轴和二维三轴两种编织形式的复合材料羽毛球拍有限元参数化模型,其中包括基质相和纤维相两相模型;其次对两种编织形式的羽毛球拍模型进行整体力学分析、失效判别分析,为其结构设计提供了理论依据;然后选取拍杆部分为研究对象进行了弹性性能预测,结果显示了有限元区域叠合法的可实施性;最后基于可视化编程软件和有限元分析软件开发了羽毛球拍尺寸设计及分析计算软件,该软件能够完成对羽毛球球拍的参数化设计和有限元分析计算。
[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.
