摘　　要：为了降低茶叶理条机在工作过程中的噪音与振动,提高机器的传动性能与茶叶的加工质量,运用遗传算法和Matlab工具箱,建立理条机传动机构的参数优化数学模型,编制目标函数与约束条件,然后通过Matlab遗传算法工具箱对参数进行优化计算并进行验证试验。优化后各参数为:理条机最小传动角为71.1°,工作行程为122 mm;极位夹角为3.6°,在优化参数下,噪音减低2 d B,茶叶成条率提高了2%。该研究为提高茶叶理条机的工作性能与延长机器的使用寿命具有重要意义。To reduce noise and vibration in working process, improve transmission performance of the machine and tea processing quality, genetic algorithms and Matlab toolbox were used to establish an optimal mathematical model of the planetary gear mechanism of the tea carding machine. The objective function and constraints were firstly set,the optimal parameters were calculated by matlab genetic algorithm toolbox and then verified by validation tests. The optimization results showed that the minimum transmission angle , working stroke , Polar angle were 71.1°, 122 mm and 3.6°, respectively. When tea carding machine was performed under optimal parameters, the noise decreased by 2 dB and the stripping tea rate increased by 2%. The study has significant importance for improving performance of tea carding machine and extending machine life.
