摘要
本文应用最小余能原理的理论和方法,对两跨和四跨全部简支边界正交异性矩形连续板结构进行动力分析,计算了全跨对称振型和反对称振型下,对应各种可能振型的固有频率,按动力学基本理论分析,结果可靠.
In this paper, the minimum excess principle method are used in all simply supported orthogonal Anisotropic continuous plate, adjacent cross with symmetry and anti - symmetry vibration modes. The natural frequencies are calculated in detail, tow - span and four - span plate. Results are reliable, according to the analysis of the basic theory of dynamics.
