摘要
本文采用样条有限点法,对多种边界条件下正交各向异性层合板的振动与稳定问题,进行了系统的分析,编制了通用程度。计算结果表明:样条有限点法在分析计算正交各向异性层合板的振动与稳定问题时,具有自由度少、收敛快、精度高、计算格式简便,易于在微机上计算等优点。
In this paper,the vibration and stability of orlhotiopic laminates with various boundary conditions are analysed by spline finite-point method (SFPM).The general program solving the problems is provided.The results show that SFPM has advantages of little freedom,faster convergence.higher accuracy and more convenience im calculation on the microcomputer. SFPM is a powerful tool in dynamic analysis and stability analysis of orthotropic laminates.
