油菜混合物与仿生筛面基体间的粘附特性

Adhesion Property between Rape Mixture and Bionic Screen Matrix

运用图像处理中的超绿特征提取与分割技术,构建油菜粘附特性测试系统,以残留粘附面积r为测量指标,引入粘附率μ和减粘率τ为衡量指标,通过粘附试验,测取并分析了油菜混合物与仿生筛面基体之间的粘附特性。试验结果表明,仿生非光滑筛面的减粘率普遍超过30%,最高达到90%,减粘作用显著;仿生凸包的减粘作用优于仿生凹坑;普通筛面的粘附程度依赖于油菜混合物的成分,而仿生非光滑筛面的粘附程度基本不依赖于油菜混合物的成分及质量比例,能在不同的收获环境与条件下保持较为稳定的减粘作用。

Rape adhesion property test system was constructed to test the adhesion property of rape mixture to bionic screen matrix,which was measured by adhesion rate μ and adhesion reduction rate τ which were correlative with residual adhesion area.Super-green feature extraction method of image technology was used to calculate the residual adhesion area.The results showed that the adhesion reduction rates τ of rape mixture to bionic screen matrix were more than 30% and even reached to 90%,which means an obvious adhesion reduction function of the bionic screen matrix.The results also showed that bionic convex surface could lower adhesion better than bionic concave surface with rape mixture.The adhesion degree of rape mixture on common screen was depend on the components of rape mixture while the adhesion degree of bionic nonsmooth screen was stable,which could adapt to different environments in the field and keep the lower adhesion function.
