阻尼减振技术被广泛应用于各种工程结构中，而寻求最佳阻尼位置又是阻尼减振技术中的一个重要问题。虽然有关此问题在理论上已有所研究。但能适用于工程应用的方法尚属少见。本文从实模态理论入手，用有限元法结合模态应变能的观点进行了结构阻尼减振最佳位置预测的研究，为工程应用提供了一种实用、简单、可靠的分析方法。 Damping vibration damping technology is widely used in various engineering structures, and to seek the best damping position damping damping technology is an important issue. Although this issue has been studied in theory. However, methods that can be applied to engineering applications are still rare. In this paper, starting from the real modal theory, the finite element method combined with the modal strain energy point of view to study the optimal position damping of structural damping research, provides a practical, simple and reliable analytical method for engineering applications.
