Abstract

Sliding plate has the problems of large sliding resistance and serious soil adhesion. Loach moves freely and flexibly in mud, has highly efficient lubrication and drag reduction effects. The sliding plate of rice direct seeding machine was selected as the research object and loach as the bionic prototype. The macroscopic and microscopic structure characteristics of loach were observed, the body surface of loach was covered by scales, which had a ridged non-smooth structure. The simulation analysis of the drag reduction performance of the non-smooth structure was carried out, the maximum drag reduction rate was 2.55% at the speed of 1 m/s. A bionic sliding plate of rice direct-seeding machine was constructed based on the non-smooth structure of loach body surface, and its working performance was simulated and analyzed. The results of orthogonal test show that the order of primary and secondary factors of bionic structure parameters affecting drag reduction rate was ribbed spacing > ribbed width > ribbed height. The optimal parameter combination was ribbing height 4 mm, ribbing width 4.5 mm, ribbing spacing, and the optimal drag reduction rate was 4.21%. The results of this study can provide theoretical support for bionic design of soil-engaging components in wet and soft paddy field.

基于泥鳅表面非光滑结构的水稻直播机滑板减阻性能研究
滑板存在滑阻大、粘土严重的问题。泥鳅在泥中运动自如、灵活,具有高效的润滑和减阻效果。以水稻直播机滑板为研究对象,泥鳅为仿生原型。对泥鳅的宏观和微观结构特征进行了观察,泥鳅体表被鳞片覆盖,鳞片呈脊状非光滑结构。对非光滑结构的减阻性能进行了仿真分析,在1 m/s速度下,最大减阻率为2.55%。基于泥鳅体表的非光滑结构,构建了一种水稻直播机仿生滑板,并对其工作性能进行了仿真分析。正交试验结果表明,影响减阻率的仿生结构参数主次因素顺序为肋间距>肋宽>肋的高度。肋高4 mm、肋宽4.5 mm、肋间距为最佳参数组合,最佳减阻率为4.21%。研究结果可为湿软水田吸土部件的仿生设计提供理论支持。
