摘要
简述了农业机械触土部件的发展及现状,归纳了可提升触土部件减阻降耗、减粘脱附和耐磨延寿等性能的诸多优化设计方法,明确了土壤性状与触土部件结构或材料之间的互作关系,提出触土部件材料的优化制造工艺,分析了仿生等先进设计方法在触土部件上的应用前景,最后总结了触土部件设计、加工等方法对现代农业机械性能的保障性作用,并对未来触土部件的研究趋势和发展方向进行了展望。
The foundation and guarantee role of the modern agriculture mechanical properties of soil- engaging components was analyzed and the primary performance parameters of soil-engaging components that need optimization at present was also summarized, which mainly included drag reduction and consumption reduction, anti-adhesion and desorption, wear resistance and life extensional and the satisfying requirements of agronomy. The main research methods to optimize the structure and properties of soil-engaging components were summarized, which mainly included clearing the interaction between soil and soil-engaging components, optimizing material composition and machining process technology, aiming at the structure function design of agronomy. And the developing orientation of agricultural machinery soil-engaging components in China was prospected, which mainly included strengthening the basic theory research, overcoming the high-performance material processing bottleneck, designing soil- engaging components by using comprehensive and advanced approach.
