摘要
为寻求梳齿式采棉机采收台结构与工作参数的最优组合,对其进行了参数优化试验。采用二次回归正交旋转中心组合优化试验方法,以行走速度、梳齿间距、梳齿振动频率为影响因素,以采净率、撞落棉率为目标函数,对影响该机采收性能的结构与工作参数进行优化试验研究。结果表明:当行走速度为0.45 m/s、梳齿间距(轴线距离)为51 mm、梳齿振动频率为2.65 Hz时,采净率为96.5%,撞落棉率为2.8%。
In order to find the optimal combination of the structure and working parameters of comb-type cotton picker harvesting device,the experiments were conducted.A central composite rotatable orthogonal experimental design of response surface methodology was employed to find the optimum combination effect on working properties.The three parameters,including working speed,comb space and vibration frequency of comb,were selected as input variables.Picking rate and loss rate were selected as response functions.Experimental results indicated that the most optimum combination region was:working speed of 0.45 m/s,comb space of 51 mm,and comb vibration frequency of 2.65 Hz,the picking rate was 96.5%,the loss rate was 2.8%.
