经验模态分解在桥梁检测中的应用
Applications of Empirical Mode Decomposition in Bridge Detecting
摘要
Abstract
This paper introduces the principle, characteristics and application of empirical mode decomposition (EMD), composites a program and verifies its'. At last, EMD is used to decompose a bridge actual signal under the condition of ambient vibration. The result indicates that EMD is a self-adapting high pass filter method without bandwidth setting in advance which is suitable for signal decomposition and mode parameter identification.关键词
