摘要
本文提出样条高斯配点法分析加劲板壳的振动与屈曲问题,文中应用双三次B样条函数作为坐标函数,应用能量原理导出了系统方程,其中包括加劲板壳的刚度矩阵,质量矩阵及几何刚阵,在推导式子的过程中,使用了高斯分片积分技术。应用Fortran77语言编制了计算机程序并在VAX-11-780超级小型机上实施了计算,文末给出若干数值算例,计算精度满意,
This paper presents a spline Gauss collocation method to analyze the vibration and buckling problems of stiffened plates and shells with various constrainted conditions. The bicubic B splines are used as coordinate functions to formulate the problem based on energy principles using the technique of piece-wise Gauss integration collocation. The accuracy of the results is compared with those calculated by other, methods and found to be in good agreement.
