| description | According to shearer vibration problems in the practical work,using multi-body dynamics theory,considering the connection characteristics between walking unit of shearer and scraper conveyor,the support characteristics of adjustment height oil vat,the stiffness of rocker arm of shearer,the connection characteristics between the parts of shearer,vibration angle of shearer,6 degrees of freedom dynamic model in the vertical direction of shearer was established.The vertical direction of shearer drum load was used as an external excitation,and the effect of different haulage speed on vertical direction vibration characteristics of shearer were solved by using numerical analysis method.The results show that the haulage speed has great influence on vibration displacement of front and rear cutting unit when the range is 2 m/min～5 m/min,the displacement range of front and rear drum is 12.3325 mm～38.9104 mm、7.5240 mm～23.7396 mm,and the displacement range of front and rear rocker arm is 4.8826 mm～15.4052 mm、3.0548 mm～9.6384 mm.Finally,the results of model is verified by experiment. |
