粘贴碳纤维布梁自由振动分析的精细积分法
High precision integration method for free vibration analysis of beam with carbon fiber
摘要
Abstract
Based on the linear elastic theories of beams and viscoelastic materials, according to Euler beam＇s equilibrium equations and geometric equations, combined with the transfer matrix method and the precise integration method, the integrated first-order ordinary differential matrix equation of debonding carbon fiber beam are derived. It consists of 8 independent firsorder differential equations and is represented by 8 variables with each variable having of homogenized precise a distinct physical meaning. The model lays a foundation for applying the technologies integration and building a semi-analytical and semi-numerical method with high efficiency and accuracy. Through the comparison of the numerical results and the results of the finite element method, it can be shown that the proposed approach is very effective and reliable.关键词
