摘要
回顾了机械振动中动态载荷识别研究的发展历程 ,对该技术的国内外研究现状及存在的问题作了综述。针对动态载荷所具有的短时、非平稳性等特点 ,指出可以利用模态滤波器、小波分析和分形过程分析等当前信号分析与处理前沿理论所具备的各自优点 ,构造高精度动态载荷识别模型 ,并对该领域今后的研究方向作了前瞻。
Being reviewed the developing experience of the dynamic force identification for mechanical vibration, an overview is presented about the research on present situation and concealed problems.In accordance with the characteristics of short time and nonstationary, it is pointed out in the paper that the force identification models with high accuracy could be established by utilizing those advantages of the theories at the leading edges for signal analysis and processing, such as modal filter, wavelet analysis and fractals. The research direction in this field is prospected as well.
