【摘要】：慣性水平振動(dòng)給料機(jī)是一種實(shí)現(xiàn)水平振動(dòng)給料的慣性振動(dòng)機(jī)械，在建材、化工、煤炭等行業(yè)均有廣泛應(yīng)用。在鋼鐵企業(yè)中，利用慣性振動(dòng)給料機(jī)為電弧爐輸送物料。本課題就是根據(jù)煉鋼企業(yè)改造電弧爐后所使用的一種新的工藝而提出的。對(duì)于現(xiàn)有的電弧爐，加料時(shí)必須首先打開(kāi)電弧爐蓋，添加鋼料后再將電弧爐蓋合上。這種進(jìn)料方式灰塵大，工人的作業(yè)環(huán)境差。針對(duì)這些缺點(diǎn)，意大利德興公司構(gòu)想在電弧爐的側(cè)壁上建個(gè)孔，利用慣性振動(dòng)給料機(jī)將鋼料直接送入爐內(nèi)，從而設(shè)計(jì)出了一種新型的電弧爐冶煉系統(tǒng)——Consteel系統(tǒng)。這樣就省略了電弧爐的開(kāi)合動(dòng)作，節(jié)省了人力，改善了工作環(huán)境；同時(shí)，電弧爐產(chǎn)生的高溫?zé)煔膺M(jìn)入到給料機(jī)封閉的料槽內(nèi)，可將鋼料預(yù)熱。 本文的主要工作有： 1.分析慣性水平振動(dòng)給料機(jī)的工作原理，建立給料機(jī)料槽、物料的力學(xué)模型，得出給料機(jī)料槽的運(yùn)動(dòng)學(xué)方程； 2.分析物料與料槽的相對(duì)運(yùn)動(dòng)情況，得出物料相對(duì)料槽三種運(yùn)動(dòng)狀態(tài)（正向運(yùn)動(dòng)，反向運(yùn)動(dòng)，相對(duì)靜止）的初始條件和終止條件，從而分析出物料的運(yùn)動(dòng)學(xué)方程； 3.利用微積分?jǐn)?shù)值計(jì)算的方法編制料槽、物料運(yùn)動(dòng)狀態(tài)的MATLAB程序，，設(shè)置相關(guān)參數(shù)，即可得到料槽、物料的運(yùn)動(dòng)仿真曲線； 4.根據(jù)平均速度的定義，計(jì)算物料的平均速度，分析影響物料運(yùn)動(dòng)的因素，改變某一參數(shù)，即可得到物料平均速度的變化曲線； 5.探究遺傳算法的優(yōu)化原理，深入理解MATLAB中遺傳算法的優(yōu)化工具箱GADS工具箱，熟悉相關(guān)的MATLAB程序的編寫(xiě)； 6.確定給料機(jī)的設(shè)計(jì)變量、約束條件，以物料的平均速度最大為目標(biāo)函數(shù)，編制遺傳算法的MATLAB程序，利用GADS對(duì)其進(jìn)行優(yōu)化，從而得到更優(yōu)的設(shè)計(jì)參數(shù)；7.對(duì)比優(yōu)化前和優(yōu)化后料槽和物料的運(yùn)動(dòng)仿真曲線，分析并得出結(jié)論。
[Abstract]:Inertial horizontal vibration feeder is a kind of inertial vibration machine, which is widely used in building materials, chemical industry, coal and other industries. This subject is put forward according to a new technology used in the transformation of EAF in steelmaking enterprises. For the existing EAF, it is necessary to open the EAF cover when feeding. After adding steel, the electric arc furnace cover is closed. This way of feeding is dusty and the workers work in a poor environment. In view of these shortcomings, the Italian company Dexing envisions the construction of a hole in the side wall of the electric arc furnace. A new type of electric arc furnace smelting system, Consteel system, is designed by using inertial vibration feeder to feed steel directly into the furnace. In this way, the opening and closing action of the arc furnace is omitted, the manpower is saved, and the working environment is improved. The high temperature flue gas generated by the arc furnace enters the closed feed tank of the feeder and preheats the steel material. The main work of this paper is as follows:. 1. The working principle of inertial horizontal vibration feeder is analyzed, and the mechanical model of feed tank and material is established, and the kinematics equation of feed tank is obtained. 2. By analyzing the relative motion of the material and the tank, the initial conditions and the termination conditions of the three moving states (forward motion, reverse motion, relative static) are obtained, and the kinematics equation of the material is analyzed. 3. The MATLAB program of material slot and material motion state is compiled by using the method of calculus numerical calculation, and the simulation curve of material motion can be obtained by setting relevant parameters. 4.According to the definition of average velocity, the average velocity of material is calculated, the factors influencing material movement are analyzed, and the change curve of average velocity of material can be obtained by changing a certain parameter. 5. Explore the optimization principle of genetic algorithm, deeply understand the optimization toolbox GADS toolbox of genetic algorithm in MATLAB, familiar with the programming of relevant MATLAB program; 6. The design variables and constraints of the feeder are determined. Taking the maximum average velocity of the material as the objective function, the MATLAB program of genetic algorithm is compiled and optimized by GADS. The results show that the better design parameters can be obtained by comparing the simulation curves before and after optimization, and then analyzing and drawing a conclusion.
