纵轴式掘进机多工况下振动特性试验研究
Experiment study of vibration characteristics for the longitudinal axial roadheader under multi-working conditions
摘要
Abstract
To master the vibration characteristics of the longitudinal-type roadheader,the in-situ vibration test over the EBJ-120TP under classic working conditions,i.e.,free loading,drilling,right-and-left cutting and downward cutting was carried out.The results were as follows:the cutting condition exhibited a random vibration characteristic compared with free loading, and was accompanied by an instantaneous impact;the roadheader vibration displayed non-stable and nonlinear feature,and had an extensive frequency scale ranging from 10 Hz to 1000 Hz;drilling was the most serious working condition,in which the cutting gear box had greatest vibration with level D(not permissible),while electronic control with level C(just tolerable);the operator would feel worst in downward cutting and drilling.Through the using of viscoelastic damping material vibration reduction measures, the vibration value of the prototype machine decreased by 30%.关键词
