【摘要】 振动传递路径系统研究是振动控制理论与技术的新颖和关键发展方向之一,在实际控制机械装备的振动实践中,多维振动传递路径系统的研究显示出了重要价值。振动传递路径系统由振动源、传递路径和接受体三部分组成,振动传递路径定义为振动产生的能量由振动源通过媒介物质传递到接受体所经历的物理介质。基于机械振动的理论,解决了多维振动传递路径的贡献量排序的问题,提出了以振动传递率为度量准则的排列多维振动传递路径的贡献量的理论方法,在频率域内清晰地阐明了多维振动传递路径贡献量的顺序。更多还原

【Abstract】 The research of vibration transfer path system is one of the new and key development directions of vibration control theory and technology. In the practical vibration control of mechanical equipment,the research of multi-dimensional vibration transfer path system has shown important value. The vibration transfer path system is composed of three parts:the vibration source,the transfer path and the receiver. The vibration transfer path is defined as the vibratory energy is transferred from the vibration source to the physical medium experienced by the receiver through the media. Based on the theory of mechanical vibration,this paper solves the problem of ordering the contributions of multi-dimensional vibration transfer paths,proposes a theoretical method of arranging the contributions of multi-dimensional vibration transfer paths based on the vibration transfer rate,and clearly clarifies the order of the contributions of multi-dimensional vibration transfer paths in the frequency range.更多还原
