摘要/Abstract

摘要： 基于Abaqus有限元分析平台,采用三维累积损伤理论和Yamada-Sun失效准则对层合板单钉连接结构的失效过程和承载特性进行了数值模拟,模拟结果与试验结果一致性较好。借助于Python语言和自编程序提出了一种层合板单钉连接结构三维有限元建模的参数化实现方法。该方法可以实现建模→分析→后处理的整个流程的自动化,极大降低了前期建模的时间成本。最后研究了几何参数、紧固件参数、载荷因素对层合板单钉连接结构承载特性的影响,研究结果表明:选择合适的板件长度、端距-孔径比、宽度-孔径比,增大孔的直径、孔的粗糙度和螺栓的预紧力可以有效提高层合板单钉连接结构的承载能力。

Abstract: Three dimensional cumulative damage theory and Yamada-Sun failure criterion are used to simulate the failure process and load-bearing characteristics of laminated plate with single joint based on ABAQUS in this paper, and the simulation results are in good agreement with the test results. A parameterized method of 3D finite element modeling of laminated plate with single joint is proposed with the help of Python language and self programming. This method can realize the automatic completion of the whole process from modeling to analysis to post-processing, which greatly reduces the time cost of early modeling. At last, the influence of geometric parameters, fastener parameters and load factors on the load-bearing characteristics of the laminated plate with single joint is studied. The results show that the load-carrying capacity of laminated plate with single joint can be effectively improved by choosing appropriate plate length, end distance to hole ratio, width to hole ratio, increasing hole diameter, hole roughness and bolt preload.

Key words: parametric method, laminated plate with single joint, three dimensional cumulative damage, bearing characteristics, composites
