摘要: 文中设计了一种基于蚁群算法的双锅曲毫机,为了提高机器的运动平顺性及降低噪音,对双锅曲毫机的曲柄摇杆机构的关键参数进行了优化设计,以其最小传动角最大化为目标函数,建立了双锅曲毫机的优化设计数学模型,运用Matlab编制了基于蚁群算法的双锅曲毫机优化设计程序,并运用此程序进行了优化计算及验证试验。优化结果表明,曲柄长度200βmm,连杆长度333βmm,摇杆长度310βmm,机架杆长度为320βmm,最小传动角由14.6º增加到21.1º,噪音由75βdB减小到70βdB,珠茶成型率由84%增加到92%,碎茶率由8.6%下降到7.2%。该研究为提高双锅曲毫机的工作性能提供了理论依据。

Abstract: In order to improve the smoothness of double-pan roasting machine and reduce the noise, the key parameters of the crank rocker mechanism of the double-pan roasting machine were optimized. The mathematical model designed for the double-pan roasting machine was set up and optimized. The objective function was to maximize the minimum transmission angle. The optimized design program of double-pan roasting machine based on ant colony algorithm was compiled with Matlab, and the optimization calculation and verification experiment were carried out with this program. The optimization results show that the lengths of crank, connecting rod, rocker and rack rod were 200βmm, 333βmm, 310βmm and 320βmm, respectively. The minimum transmission angle was increased from 14.6 to 21.1, and the noise was reduced from 75βdB to 70βdB, the forming rate of gunpowder tea increased from 84% to 92%. The rate of broken tea decreased from 8.6% to 7.2%. This research provided a theoretical basis for improving the performance of double-pan roasting machine.
