（摘要）
首先应该对抓斗进行设计计算，确定抓斗的各个参数，然后根据抓斗的型号、起重量和给定的起升高度、起升速度，确定起升机构的布置方案，然后确定钢丝绳的型号，选取合适的卷筒、滑轮直径。根据设计计算选定减速器、电动机、制动器和联轴器。根据设计计算的结果，绘制出抓斗部件图和起升机构总体装配图。
对抓斗的优化主要是通过MATLAB语言，将前面已经设计好的抓斗参数转化为线性方程，这个过程和其它调式程序一样，主要包括这样几个步骤：编辑.编译.连接.以及执行和调试。利用MATLAB软件可以求解线性规划、无约束规划、二次规划和有约束非线性规划等优化设计问题.该软件编程工作量小,初始参数输入简单,符合工程设计语言,有着很大的优越性.通过给出的优化实例可以看出,应用该软件求解机械优化设计问题非常方便。

Design and optimization for the grab of structural
（Abstract）
First should carry on the design calculation to the grab, definite grab each parameter, then according to the grab model, the lifting capacity and assigns lifts, lifts highly the speed, determined lifts the organization scheme of arrangement, then the determination steel wire model, selects the appropriate reel, the pulley diameter. According to design calculation designation reduction gear, electric motor, brake and shaft coupling. According to the design calculation result, draws up the grab part chart and lifts the organization overall assembly drawing.
To the grab optimization mainly is through the MATLAB language, front already will design the grab parameter transformed as the linear equation, this process and other mode procedure were same, mainly included such several steps: Edition.Translation.Connection.As well as execution and debugging. May solve the linear programming, the non-restraint plan, two plans using the MATLAB software and has optimized design questions and so on restraint nonlinear programming.This software programming work load is small,The initial parameter input is simple,Conforms to the engineering design language,Has the very big superiority.Through the optimized example which gives may see,Solves the machinery using this software to optimize the design question to be extremely convenient.
