Abstract

The invention relates to an optimized design method for a hydraulic cylinder supporting seat of a cover carriage based on a response surface, which is a method for predicting and optimizing an optimized design scheme of the hydraulic cylinder supporting seat based on a difference fitting theory of the response surface; the method comprises the steps of: (1) determining a basic outline and a primary dimension of the hydraulic cylinder supporting seat; (2) analyzing and defining dimension variables, a domain of definition and interactive restraint relation of affecting the shape of the hydraulic cylinder supporting seat; (3) sampling the space by a Latin hypercube test design method; (4) analyzing the stress response of the hydraulic cylinder supporting seat via a finite element method; (5) creating a response surface model and estimating the model precision; and (6) creating an mathematic optimization model, calculating the minimal stress value, and verifying the minimal stress value by the finite element method, and determining the optimized design scheme of the supporting seat. According to the invention, the calculation time is greatly shortened, the calculation cost is reduced, and a high-quality and reliable design scheme of hydraulic cylinder supporting seat of cover carriage can be obtained.

Description

technical field [0001] The invention relates to an optimal design method for a hydraulic cylinder support seat of a capping machine, in particular to an optimal design method for a hydraulic cylinder support seat of a capping machine based on a response surface, and belongs to the technical field of blast furnace smelting. Background technique [0002] Environmental protection requirements for blast furnace smelting are getting higher and higher. At present, new blast furnaces basically require the use of capping machines. The function of the uncapping machine is to move the trench cover, cover the trench cover when the blast furnace is tapping (to avoid dust, splash, heat radiation, etc.), and remove the trench cover after the molten iron is discharged. During maintenance, the cover removal machine needs to move the trench cover to the area where the maintenance crane can work. [0003] Rotary decapping machine (patent publication number: CN 101445846A) has the characteris...
