摘　　要：以东北农业大学培育的4种稻谷品种为试验材料,在测量装置上分别测定稻谷种子除芒前、后滑动摩擦角、休止角、内摩擦角。结果表明,稻谷种子滑动摩擦角、休止角、内摩擦角有差异,且除芒后其值均比除芒前小。除芒稻种在铁板、尼龙板、橡胶板三种材料上滑动时橡胶板摩擦力最大,可以考虑用橡胶材料作为除芒机的动杆。Gliding friction angle, stop-angle, inner friction angle of awned seeds of four kinds of rices were measured and analyzed. The results showed that the gliding friction angle, stop-angle, inner friction angle of rice seeds were higher than awned rice seeds. These parameters can be used as the basis to design the awner for paddy keneral.
