摘要
用ＷＰＡ法推导出了任意多支承梁（ｎ≥２）的动特性分析计算方法．将ＷＰＡ法与经典解析法的计算结果进行了对比，并用ＷＰＡ法具体分析了某潜艇四支承桅杆的动响应、模态振型和应力分布．结果表明ＷＰＡ法具有计算速度快。
Dynamic analysis and computation method of multiple supported beam ( n ≥2) has been derived by use of WPA method. The computational results obtained by WPA and classical methods have been compared respectively. Taking 4 supports submarine mast as an example, the dynamic response, modal shape and stress along the mast are given. The calculation results show that this method has the superior advantages in computation speed, precision and damping effects of beams.
