摘　　要：TQLZ100×200振动清理筛支撑位置改变对振动清理筛清理效果有重要影响,其连接弹簧与筛体支座加强筋处是振动清理筛的薄弱部位,极易受损。基于能量原理,利用朗格朗日方程建立了TQLZ100×200振动清理的运动微分方程,采用数值方法对微分方程进行了求解分析,获得了振动清理筛在垂直方向上的运动规律。在分析其运动规律的基础上,探究了不同支撑位置对振动清理筛垂直方向上运动的影响,获得了筛体垂直方向上的运动规律与支撑位置关系模型,为提高振动清理筛的筛分效果和延长其使用寿命提供了依据。For the TQLZ100×200vibration cleaning sieve supporting position＇s changes had a significant impact on the cleaning effect,and the reinforcement of the support which connected with a spring and a sieve body was a weak part of the overall strength of vibrating screen,which was very easy to damage,based on the principle of energy,we established TQLZ100×200differential equations of motion of cleaning vibration using Lagrange equation.The differential equations were solved using numerical method,and the motion law of the vibrating sieve in the vertical direction was obtained.Based on the analysis of the motion law of the vibration sieve,we explored the different effects of the vertical direction movement of the supporting position on the vibration sieve and got the relationship model of the sieve body vertical movement and the supporting position,which improved the screening effect and prolonged the service life of the vibration cleaning sieve.
