分析机械结构动态设计的几项关键技术：准确方便地辨识结构的结合部参数与结构的阻尼矩阵；高效精确的、并与动态设计相适应的有限元模型实验修正；以结构设计变量为优化变量的动力学逆问题直接求解；动力学正问题方法中快速准确的重分析。在叙述这些关键技术的国内外研究现状基础上，指出在未来一段相当长时间内，该领域的研究重点仍是这些关键技术，以及与其相关的商品化集成软件开发。
This paper analyzes several key technologies of dynamic design of mechanical structure: accurate and convenient identification of structural parameters and structural damping matrix; efficient and accurate finite element model experimental adaptation to dynamic design; structural design variables as optimization variables The direct solution of kinetic inverse problem; fast and accurate reanalysis in the method of dynamic positive problem. Based on the domestic and foreign research status of these key technologies, it is pointed out that for a long time to come, the key technologies in this field are still concerned with the development of commercially available integrated software.
