Biomechanical analysis of the contact interface between crops and agricultural machinery: Mechanical behavior and crop damage mechanisms in field operations
Abstract
In this article, it investigates the relationship between biomechanical properties and its contact interface between crops and agricultural machinery, thereafter the procession of how could biomechanical properties affect the mechanical behavior with relative crop damage mechanisms during harvest operation was discussed. This paper first gave an overall perspective of the mechanical features of pressure, friction, and shear forces about the interface between agricultural machinery and crops, thereafter came up a conclusion that these features shall be the essential factors causing crop damage during harvest. Through the analysis of how biomechanical force impacts corps during harvest operation, one step more, relevant mechanisms were revealed in the cellular structure and physiological and biochemical scales about how these mechanical properties worked on crops, in the result causing damage. Furthermore, this article gave a brief discussion about the mechanical behavior with crop damage mechanisms during harvesting, and came up with some potential strategies in optimizing agricultural machinery design and operating methods to reduce crop damage. This result indicates that improvements such as adjusting mechanical structures, standardizing harvest operation tactics, and adopting biomimetic principles can effectively reduce the mechanical stress of the contact interface thereafter minimize crop damage. In conclusion, this article summarizes the current research achievements and proposes future research directions, including in-depth study of crop damage mechanisms, and improvement of new agricultural machinery, in order to further promote the sustainable development of agricultural production.
