摘要
液压管路系统由于存在多物理场、多尺度及流固耦合非线性等特性,因此其振动特性复杂,且危害很大。又由于工业生产的需求,液压系统正逐步向高压高速和高功重比方向发展,又使得液压管路振动的产生和传播机理变得更为复杂。因此有必要对液压管路的振动机理和控制方法及其研究现状进行总结和分析。阐述液压管路振动的危害性和复杂性,并结合近十年来国内外专家学者对于液压管路振动模型的研究内容,在对考虑多场、多尺度及流固耦合因素影响的液压管路振动机理进行总结的基础上,对液压管路流固耦合线性化动力学模型和非线性振动模型的研究成果进行分析,并对液压管路被动、主动及半主动振动控制的研究进展及研究成果进行评述,在此基础上提出今后液压管路系统流固耦合振动机理及振动控制研究的发展趋势。
Because of the effects of multi-physics,multi-scale and fluid-structure interaction（FSI）,the vibration characteristics of the hydraulic pipeline system is not only complex,but also harmful.Due to the demand of the industrial production,the hydraulic system is gradually to develop in the direction of high pressure,high speed and high power ratio,which makes the production and propagation mechanism of hydraulic pipeline vibration become more complex.So it is necessary to summary and analyze the research status of the vibration mechanism and control method of hydraulic pipeline.Harmfulness and complexity of hydraulic pipeline vibration are expounded.Combined with the research on hydraulic pipeline vibration and dynamic model which the domestic and abroad experts are committed to in last ten years,hydraulic piping vibration mechanism,in which effects of multi-physics,multi-scale and FSI is taken into account,is summarized.On this basis,some research such as hydraulic pipeline of FSI linear dynamic model and nonlinear vibration model are analyzed,too.Research on vibration control method of hydraulic pipeline is also analyzed,such as active vibration control,passive vibration control and semi-active vibration control.The development tendency of FSI vibration mechanism and control of hydraulic pipeline are proposed.
