摘要
针对目前在用的闸阀普遍笨重,运输、安装不便等问题,对其进行了基于MATLAB的阀体优化设计。以阀体内径、壁厚和高度为设计变量,以阀体实心部分体积最小为目标函数,以强度、变量非负等为约束条件建立优化模型。使用MATLAB优化工具函数,按照所建模型的约束条件和目标函数建立.m文件,调用优化工具函数fmincon对问题进行求解。优化算例表明,所得的最优点位于所有约束条件交集上,阀体体积减小了28.65%。
For the inconvenience of transportation and installation of the current gate valve owing to its heaviness, the optimum design of valve body is carried out based on MATLAB. The optimization model is established with the internal diameter, wall thickness and height of the valve body as design variables, the solid volume of the valve body as object function and the strength and variable non-negative as constraint conditions. The .m file is established according to the constraint condition and object function of the established model by using the MATLAB optimized tool function, and the optimized tool function fmincon is used to solve the problem. The optimized calculation example shows that the obtained optimum point is at the intersection of!all the constraint conditions with the valve body volume decreased by 28.65%.
