摘要
运用统计能量分析方法分析机械设备连结部位的功率流及功率在该处的损耗和传递,建立结构总体统计能量分析(SEA)模型,根据结构功率平衡方程,推导出非保守耦合损耗因子的计算公式。基于这些,对一个实际机械设备联接部位计算例子,进行了详细的理论推导、仿真数值计算与分析,提出了一些有工程应用价值的结论。
In this paper.SEA method is applied to analysis the power flow,dissipating and transmission of the joints.The SEA model of the whole structure is built up,and the computation equation of non-conservatively CLF is deduced out based on the structure' power equality.The theoretical dedution,simulate mathematics calculation and analysis of an actual mechanic equipment joint are given explicitly,including some valuable conclusion on structural apply.
