结构振动阻尼理论模型探究及实验分析
|
摘要
阻尼是结构的重要动力特性之一,是结构抗震分析中的重要因素,但出于简单易行的考虑,现行阻尼理论多采用或简化为黏滞阻尼理论。本文对结构振动中的阻尼理论在综合分析的基础上提出了一种新的加速度阻尼模型,经过理论推导、模型振动实验和数据分析,验证了这种阻尼理论的合理性与可行性,弥补了黏滞阻尼理论在物理学解释与实际应用时的不足,并且在一定程度上简化了工程应用中的振型分解法。
Damping is one of the important dynamic characteristics of structure,but for simplicity consideration,viscous damping theory is often adopted or simplified as viscous damping theory. This paper puts foward a new acceleration damping model on the basis of damping theory in structural vibration on the comprehensive analysis,through theoretical analysis and model experiment and data analysis,to verify the rationality and feasibility of the damping theory. We make up the deficiencies in physical interpretation and practical application of the damping theory,and simplify the system decomposition method in engineering application to a certain extent.
