摘要
本文研究预应力条件下轴对称简支和固支圆板的瞬态响应,利用振型展开和Laplace变换给出解析表达式,提出简化型圆板的边界条件,利用Hankel变换和Laplace变换给出简捷的解,针对几种边界状态,比较了其频率和响应,同时讨论了几种常见的瞬态载荷的结构响应形式。
The expressions of the frequencies and displacements for the axisymmetrical circular plate clamped or simply supported under the prestressed conditions are presented in mis paper. It is assumed that a simplified boundary condition may be used for the circular plate,then the convenient solution can be deduced from hankel and Laplace transforms. The response of the prestressed plates subjected to some typical transient load is discussed.
