摘要
以同一运载火箭发射不同有效载荷的实际需要为应用背景，引出了动力学接口的概念，阐述了这一概念在振动环境试验条件的制定和试验模态分析中的应用，讨论了界面自由度的确定原则和动力学接口参数的分析和实测方法。
The concept of the dynamical interface is introduced for application of dynamics analyzing for similear carrier rocket with different payload. The finding of vibration environment test specification and the modal analysis by this concept is described. The foundation of finding interface degree of freedom and the analysis and measure method of dynamical interface parameter is discussed.
