自由界面法的若干新品种

Some New Varieties of Free-Interface Methods for Dynamic Substructural Coupling

本文利用一种实用完备模态集作为里兹基底建立了若干新的自由界面模态综合法品种,有精确的和近似的.不过本文仅详细叙述了近似自由界面法和两种综合步骤.由混合空间综合步骤之算例考核的成功可以推知,其它新自由界面法形式也应该能获得满意的结果.

Some new varieties of free-interface methods for coupling dynamic substructures are developed by using a practical complete modal set in this paper, in which there are accurate and approximate ones. However the present paper describes only in detail the approximate method and two substructural assembling procedures, i.e. the modal space assembling procedure and the hybrid space one. An example used to examine the hybrid space method is successful,thus it is known that other kinds of free-interface methods described in the paper should obtain also the satisfied results.
