| 摘 要： | 针对石榴脱粒机器脱净率低、破损率高等问题,设计了一种振动式石榴脱粒装置。首先,阐述装置的整体结构和工作原理,根据理论分析及前期试验确定以曲柄长度X1、曲柄转速X2及振动盘转速X3为试验因素,将石榴脱净率Y1和破损率Y2作为目标响应值;然后,通过Design-expert软件对目标响应值进行数据分析,得到影响石榴脱净率Y1的显著顺序为曲柄转速X2>振动盘转速X3>曲柄长度X1,影响破损率Y2的显著顺序为曲柄转速X2>曲柄长度X1>振动盘转速X3。试验验证结果表明:当曲柄长度X1为57mm、曲柄转速X2为139r/min、振动盘转速X3为29r/min时,石榴脱净率Y1为95.58%,破损率Y2为2.38%,试验值与优化结果的相对误差分别为1.37%、3.03%,均小于5%。

| Abstract: | At present,a vibrating type pomegranate threshing device has been designed for the problems of low removal rate and high damage rate of pomegranate threshing machines.First,the overall structure and working principle of the device are explained.According to theoretical analysis and preliminary tests,it was determined that the crank length X1,crank speed X2 and vibrating plate speed X3 were the test factors,and the pomegranate threshing rate Y1 and broken rate Y2 were used as the target response values,and then the target response values were measured by the Design-expert software.According to the data analysis,the significant order that affects pomegranate threshing rate Y1 was:crank speed X2>vibrating plate rotational speed X3>crank length X1,and the significant order affecting broken rate Y2 was:crank rotational speed X2>crank length X1>vibrating plate rotational speed X3.It was verified by experiments that when the crank length X1 was 57 mm,the crank speed X2 was 139 r/min,and the vibrating plate speed X3 was 29 r/min,the pomegranate threshing rate Y1 was 95.58%,and the broken rate Y2 was 2.38.%,the relative error between the experimental value and the optimized result was 1.37%and 3.03%,both are less than 5%. |
