　　利用斜面式农业物料摩擦因数自动测量试验台，测定了不同斜面倾角、品种和取样方向的龙眼果壳—橡胶板、果壳—尼龙板之间的摩擦因数以及果肉的摩擦因数。结果表明，龙眼果壳—橡胶板的静摩擦因数为0.828～0．902，滑动摩擦因数为0．660～0．757；果壳—尼龙板之间的滑动摩擦因数为0．608～0．658；果肉的静摩擦因数为0．113～0．185。因此，利用龙眼果肉、果壳与橡胶板之间的摩擦因数不同，可以实现果肉、果壳的分离。

Based on the automatic agricultural materials friction coefficient measuring device ,the friction coefficient be-tween the Longan shell and rubber plate , shell and nylon plat were measured for different varieties ,sampling directions and slope angle.The result showed that the static friction coefficient between Longan shell and rubber plate was 0.828-0.902,the sliding friction coefficient between Longan shell and rubber plate was 0.660-0.757, the sliding friction coef-ficient between shell and nylon plate was 0.608-0.658.The static friction coefficient between Longan pulp and rubber and nylon plate was about 0.113-0.185.So we can separate longan pulp with shell with the different friction coefficient shell and pulp.
