    摘要:

    结构的高频振动问题严重影响着飞行器的服役安全性、可靠性和舒适性,高效准确地预示结构的高频振动响应具有重要的学术研究价值和工程实践意义。能量有限元法是近年来发展起来的一种高频振动响应预示新方法,弥补了有限元法、统计能量法等传统方法在高频振动响应预示方面的不足。本文回顾了能量有限元法的研究进展,阐述了能量有限元法的基本理论及其在工程领域的拓展和应用,对能量有限元法在飞行器结构高频振动响应预示方面的研究工作进行了介绍,并对能量有限元法未来的发展方向进行了展望。

    Abstract:

    The high-frequency vibration problem of structures seriously affects the service safety, reliability and comfort of the aircraft. It is of great academic value and engineering significance to predict the high-frequency vibration response of structures efficiently and accurately. The energy finite element method (EFEM) is a new method developed in recent years to predict high-frequency vibration response. It overcomes the shortcomings of traditional methods such as the finite element method (FEM) and the statistical energy analysis (SEA) in predicting high-frequency vibration response. In this paper, the research progress of the energy finite element method in recent years are reviewed. The basic theory of the energy finite element method and its extension and application in engineering are elaborated. Studies of the energy finite element method in predicting the high-frequency vibration response of aircraft structures is introduced. In addition, the future directions of the energy finite element method are prospected.
