压路机双轮振动对整机减振性能的影响

Effect of Tandem Vibratory Roller under Double-Drum Vibration

减振问题一直是困扰双驱、双振铰接式双钢轮振动压路机的主要问题之一.现有的分析方法忽略两个钢轮振源的相互影响.采用试验的方法研究一级减振中,两个振源的相互影响及机架自身的摆振问题.工业样机的试验结果表明:双钢轮振动压路机机架的振动是复杂的振动合成,包含前、后振动源相互影响、车架摆振、减振器造成的振动滞后等;其中,前、后钢轮两个振源相互影响及机架本身的摆振对机架的振动影响较大.

Vibration reduction has been one of the main problems of double-drum vibratory roller which has two drive systems and two vibration systems.Traditional linear theory can not satisfactorily solve the problem of the machine.This paper did the industrial prototype vibration tests to study the dynamic characteristics of isolation system on tandem vibratory roller.In this paper,the tandem vibratory rollers isolation systems research focused on how to reduce the vibration in the rack through experimentation.The experimental results show that： the vibration of the tandem vibratory roller rack is a complex synthesis,which contains two frequency vibrations generated by the interaction,frame shimmy,and the lag damper vibration of the rack itself.In all the vibration components,the majority are two frequency vibrations generated by the interaction and frame shimmy.
