基于ANSYS的纤维增强塑料接头连接件性能研究和结构优化

PERFORMANCE RESEARCH AND STRUCTURAL OPTIMIZATION OF FIBER REINFORCED PLASTIC CONNECTOR CONNECTORS BASED ON ANSYS

通过有限元分析的方法对纤维增强塑料接头连接件的连接方式和性能进行研究和结构优化,并结合实验法对分析结果进行验证。研究表明:机械连接因为螺栓处的应力集中,不适合作为主要受较大拉伸应力的纤维增强塑料的接头连接结构;双搭接板对接的胶接连接方式具有较小的等效应力、总体形变和接触面应力,不易发生剥离破坏,说明双搭接板对接宜作为纤维增强塑料的接头连接方式,这和实测法测得结果一致,同时验证了ANSYS有限元分析在纤维增强塑料的接头连接件的性能研究中的适用性。最后基于搭接长度对接头结构进行优化,结果表明搭接长度为70 mm的双搭接板对接方式为优化结构。

The connection mode and performance of fiber-reinforced plastic connector connectors are studied and structural optimization are studied by the method of finite element analysis,and the analysis results are verified by the experimental method.The results show that mechanical connections are not suitable for joint connection structures of fiber-reinforced plastics that are mainly subject to stretch stress because of the concentration of stress at the bolts,and the plying connection methods of the double-tie board docking have smaller equivalent stresses,overall deformation and contact surface stress,and are not prone to peeling damage.It is shown that the docking of the double-connecting plate should be used as a joint connection method,which is consistent with the measured results,verifying the applicability of ANSYS finite element analysis in the performance study of fiber-reinforced connector connections.Finally,the joint structure is optimized based on the tie-up length,and the results show that the docking method of the double hooking plate with a connection length of 70 mm is optimized.
