摘　　要：基于当前海洋疏浚中的常用小容积抓斗,进行静力学分析,抽象出其数学模型,研发并推导出50m3级别的疏浚抓斗力学和数学模型。以斗齿受力作为目标函数,系统地提出设计疏浚抓斗中各结构件的比重参数关系。设计CAD力学结构模型,通过Workbench进行斗齿受力分析,给出适合50m3级别疏浚抓斗参数设计公式及CAE分析。On the basis of small volume grab which is used commonly in current marine dredging, its mathematical model is static analyzed, then the static and mathematical models of 50 m3 levels dredging grab are deduced and developed. Taking the stress of bucket teeth as the objective function, the proportion parameter relationship of each structural component in designing dredging grab is systematically proposed. The CAD mechanical structural model is designed, the stress of bucket teeth is analyzed by Workbench software, and then the suitable design formula and CAE analysis are given.
