摘　　要：为改善荔枝的采摘条件,提高其采摘效率,通过分析荔枝的栽培生长特性,设计了一种简易且不伤果的荔枝串果采摘器具;建立了采摘器剪切运动和剪切力模型,利用Matlab进行了结构参数优化;应用Adams和AN-SYS构建了采摘器虚拟样机及有限元模型,进行了运动仿真分析和强度分析,验证了采摘器整体设计和结构参数的合理性。采摘试验表明,采摘器样机可快速采摘且柔性接果。In order to improve litchi harvesting conditions and raise working efficiency,a simple and no-damage litchi string-fruit harvesting device was designed by analyzing the growth characteristics of litchi.The shearing movement and shear stress model were established,and their structural parameters were optimized in Matlab.Meanwhile,Adams and ANSYS software were used to build virtual prototyping and finite element model of the harvesting device.By the motion simulation analysis and strength analysis,the rationality of whole design and construction parameters were verified.The harvesting experiment showed that the prototype can fast harvesting and flexible receive.
