基于人工蜂群算法的高速变螺距分件供送螺杆优化设计

高速变螺距分件供送螺杆是包装机械中供送系统的重要基础构件,是整个设备的咽喉。研究提出用人工蜂群算法优化螺杆结构参数,高速变螺距分件供送螺杆优化模型以螺杆螺旋线总长最小为优化目标,以螺旋线最大圈数为设计变量,以供送过程中螺杆对包装容器保持有阻挡作用,以及加速度的最大变化率小于预定值为约束条件。结果表明,经过人工蜂群算法优化后获得的最优螺旋线最大圈数能有效减小高速变螺距分件供送螺杆的长度,为高速变螺距分件供送螺杆参数的合理选取提供了依据。

Optimization of high speed variable pitchtiming screw based on artificial bee colony algorithm

High speed variable pitch timing screw is an important foundation component of feeding system in packaging machinery. It is the throat of the whole equipment. In this paper, the artificial bee colony algorithm is employed to optimize the structure parameters of the screw, providing a basis for the design of maximum number of circles. The high speed variable pitch timing screw optimization model takes the minimum total length of the variable pitch screw helix as the optimization goal, with maximum number of helix circles as design variables, the plugging effect on the packaging container is kept, as well as the rate of acceleration change is no more than the predetermined value as the constraint conditions. The results show that the maximum numbers of helix circles obtained by artificial bee colony algorithm can effectively reduce the total length of variable pitch timing screw. It is useful for the reasonable selection of high speed variable pitch timing screw structure parameters.
