摘要
本文运用能量近似法及广义梁函数,求解了各种长宽比的矩形薄板在十八种边界条件下的自由振动频率,其结果与以往文献比较,具有很高的精度,但计算工作量大为减小。
By making we of the Kantorovich energy approximation method, with the generalized beam functions, this paper find out the free vibration frequencies of the rectangular thin plates with various aspect ratios under the eighteen types of boundary conditions. Compared with the available literatures, the obtained results possess very high accuracy but the computing amount of work is remarkably reduced.
