Vibration Balance Optimization of Nipper Mechanism Structure in Comber

探讨精梳机钳板机构振动平衡优化的方法。从钳板往复摆动产生的惯性力是引起精梳机振动的主要因素出发,利用惯性力的合成原理分析了钳板机构振动平衡优化的过程。运用动力学仿真软件ADAMS,以配重质量、质心位置、方位角为设计变量,以迭加后的钳板机构总惯性力幅值最大值为目标函数,对钳板机构进行振动平衡优化。结果表明,当配重质量为6kg、质心位置为43.7mm、方位角为38.1°时,优化效果较好,精梳机钳板机构惯性力幅值减小了58.1%。认为,运用ADAMS软件进行精梳机钳板机构振动平衡优化,过程简单、结果准确,效果明显。该方法也适用于其他机械机构。

The method of vibration balance optimization of nipper mechanism structure in comber was discussed. Inertia force generated for the reciprocate swing of nipper mechanism structure was the main element cause for the vibration of comber. Started with this, process of vibration balance optimization for nipper mechanism structure was analyzed using composition theory of inertia force. Dynamics simulation software ADAMS was adopted. Counter weight,location of mass center and azimuth angle were used as design variable. The maximum amplitude of total inertia force on nipper mechanism structure after superposition was taken as objective function. Vibration balance optimization of nipper mechanism structure was implemented. The test results show that the optimization effect is the best with inertia force reduction of nipper mechanism structure in comber as 58. 1 when counter weight is 6 kg, mass center location is 43.7 mm and azimuth angle is 38.1°. It is considered that the process of using ADAMS software for vibration balance optimization of nipper mechanism structure in comber is simpler, test results are more accurate, the effect is more obvious, The method is also suit for other machineries.
