    摘要:

    莖稈是農(nóng)作物的主要副產(chǎn)品,也是世界范圍內(nèi)豐富的生物質(zhì)資源。莖稈切割是剛性體與柔性體的直接互作過程,是莖稈處理的重要工序,。莖稈切割與農(nóng)作物高效低損傷收獲及莖稈資源化利用密切相關(guān),開展割刀與莖稈切割互作過程的研究是農(nóng)藝農(nóng)機深度融合的重要方面,,對于農(nóng)業(yè)生產(chǎn)與生態(tài)發(fā)展具有現(xiàn)實意義,。為此,本文圍繞莖稈切割的相關(guān)問題進行了國內(nèi)外研究進展的綜合評述與分析,,具體為:圍繞莖稈力學參數(shù)與本構(gòu)模型,,闡述了莖稈生物學特征與力學參數(shù)的關(guān)系、測試方法與設(shè)備,、莖稈本構(gòu)模型的建立及應(yīng)用,;結(jié)合割刀結(jié)構(gòu)參數(shù)與型式、耐磨性能,、自磨銳性能,,介紹了割刀的結(jié)構(gòu)型式與材料特性;針對割刀與莖稈的切割互作過程,,系統(tǒng)介紹了切割原理,,以及高效率、低功耗,、低損傷等切割技術(shù)研究目標,;從試驗研究的具體參數(shù)及目標值到仿真研究的不同類型,梳理了兩種研究方法在莖稈切割中的應(yīng)用概況,。在此基礎(chǔ)上,,結(jié)合現(xiàn)有問題,著重探討了莖稈切割領(lǐng)域未來的發(fā)展方向,,為農(nóng)業(yè)生產(chǎn)中莖稈切割問題的深入研究提供了參考,。

    Abstract:

    Stalks are not only the main by-products of crops, but also abundant biomass resources in the world. Stalk cutting is a direct interaction process between rigid body (machinery parts) and flexible body (stalks), which plays a pivotal role in the treatment of stalks. The cutting performance of machinery, the biological characteristics of the stalks, and the coupling between them all affect the cutting process. Stalk cutting is closely related to the efficient and low damage harvest of crops and the comprehensive utilization of stalk resources. The research on the cutting interaction process between cutting blades and stalks is an important aspect of the deep integration of agronomy and agricultural machinery, which has practical significance for agricultural production and ecological development. To this end, a comprehensive review and analysis of research progress at home and abroad around the related issues of stalk cutting was made, specifically as follows: focusing on mechanical parameters and constitutive model of stalks, the relationship between biological characteristics and mechanical parameters, testing methods and equipments, establishment and application of constitutive model of stalks were described; combined with the structural parameters and types, wear resistance and self-sharpening performance, the structural types and material properties of the cutting blades were introduced; according to the cutting interaction process between cutting blades and stalks, the cutting principle and the cutting technical objectives of high efficiency, low power consumption and low damage were systematically introduced; from the specific parameters and target values of experimental research to the different types of simulation research, the application of the two research methods in stalk cutting was summarized. On this basis, combined with the existing problems, the future development directions of stalk cutting field were discussed. It contributed to comprehensively understanding the phenomenon of stalk cutting and providing a reference for the in-depth research of stalk cutting in agricultural production. 
