摘要
通过对曲柄群驱动机构平面内的惯性力与惯性力矩分析,建立了该机构动力优化平衡模型。以3个曲柄副的曲柄群机构为例,利用Matlab优化工具箱对具体优化模型进行了求解。结果表明,曲柄群驱动机构动力优化平衡方法能够大幅度降低机构的惯性力与惯性力矩,并且优化平衡时仅需要根据优化结果,在曲柄长度反方向的确定位置附加确定质量的平衡质量块即可,该方法具有较高的可操作性与实际应用价值,对该机构的快速平衡和推广应用具有一定指导意义。
By analyzing the inertia force and inertia moment in the plane of crank-group driving mechanism,the dynamic optimization balance model of the mechanism is established.Taking the crank-group mechanism of three crank pairs as an example,the specific optimization model is solved by using Matlab optimization toolbox.The results show that the dynamic optimization balance method of crank-group driving mechanism can greatly reduce the inertial force and moment of inertia of the mechanism,and the optimization balance only needs to add the balance mass of the determined mass at the determined position in the opposite direction of the crank length according to the optimization results just a couple of pieces.This method has high operability and practical application value,and has certain guiding significance for the rapid balancing and popularization of the mechanism.
