肋板结构功率流的理论研究

THEORETICAL STUDIES ON POWER FLOW OF THE PLATE ASSEMBLIES WITH THE RIBS

基于机械导纳和弹性结构动力学的原理与分析方法，首次推导了加肋板结构功率流的解析表达式，并对这些表达式进行了数值计算，给出了典型加肋板结构功率流的算例。这些板结构功率流的理论结果，对机械工程中广泛应用的板结构及其由它们组成的复杂结构的动态特性分析。优化设计和振动、噪声控制，具有重要的理论指导和工程技术意义。

Based on the principles of mechanical mobility and structural dynamics some theoretical formulae of the plate assemblies with the ribs are preaented. some numerial results and computing examples are also given.These theoretical formulae will provide some principles for the dynamical analysis and noise, vibration control in the structures applied widely in engineering.
