【摘要】：隨著科技的進(jìn)步與經(jīng)濟(jì)的發(fā)展,鋼鐵產(chǎn)業(yè)作為國家經(jīng)濟(jì)的支撐產(chǎn)業(yè)之一,逐步走向繁榮。在鋼鐵生產(chǎn)與加工過程中,熱處理工藝不僅是一道重要工序,還是提高材料強(qiáng)度最重要的手段。大型鋼板進(jìn)給機(jī)構(gòu)是將鋼板輸送到加熱爐中進(jìn)行熱處理的設(shè)備,設(shè)備運(yùn)轉(zhuǎn)的好壞,直接影響鋼板加工的效率。人們往往將進(jìn)給機(jī)構(gòu)作為多種熱處理設(shè)備之一進(jìn)行研究,然而專門針對進(jìn)給機(jī)構(gòu)的研究甚少。隨著現(xiàn)代社會對高強(qiáng)度鋼板需求的增加,鋼板進(jìn)行熱處理的要求也會越來越多,鋼板進(jìn)給機(jī)構(gòu)使用的頻率就會隨著提高,無論從安全方面和還是從經(jīng)濟(jì)方面考慮,對進(jìn)給機(jī)構(gòu)結(jié)構(gòu)的研究都是很有必要的。 首先,本文從力學(xué)的有關(guān)理論知識著手,著重研究了某進(jìn)給機(jī)構(gòu)的運(yùn)動和受力情況,闡述了結(jié)構(gòu)力學(xué)、有限元分析理論與方法、有限元分析軟件,以及可靠性分析理論及方法等理論方面的知識。其次,通過對進(jìn)給機(jī)構(gòu)的運(yùn)動和受力分析以及基于ANSYS的有限元分析,計(jì)算分析出進(jìn)給機(jī)構(gòu)中不合理的設(shè)計(jì),由此對進(jìn)給機(jī)構(gòu)的設(shè)計(jì)作出調(diào)整。最后,對新的方案進(jìn)行運(yùn)動和受力分析以及強(qiáng)度校核,重點(diǎn)對改進(jìn)后的方案進(jìn)行基于蒙特卡羅法的有限元法可靠性分析,得出在置信度為95%的條件下,改進(jìn)后的大型鋼板進(jìn)給機(jī)構(gòu)的翻轉(zhuǎn)臂、主軸及車架所受應(yīng)力值都小于其屈服強(qiáng)度,結(jié)構(gòu)可靠。
[Abstract]:With the progress of science and technology and the development of economy, the iron and steel industry, as one of the supporting industries of the national economy, has gradually become prosperous. In the process of steel production and processing, heat treatment is not only an important process, It is also the most important means to improve the strength of the material. The feeding mechanism of large steel plate is the equipment for heat treatment of the steel plate in the heating furnace, and the equipment is good or bad in operation. The feed mechanism is often regarded as one of the kinds of heat treatment equipment, but the research on the feed mechanism is very few. With the increasing demand of high strength steel plate in modern society, the efficiency of steel plate processing is directly affected. The requirement of heat treatment of steel plate will be more and more, and the frequency of the feed mechanism will increase with the increase of the frequency. It is necessary to study the structure of the feed mechanism both from the safety and economic aspects. First of all, based on the theory of mechanics, this paper mainly studies the movement and force of a certain feed mechanism, expounds the structural mechanics, the theory and method of finite element analysis, the software of finite element analysis. Secondly, through the motion and force analysis of the feed mechanism and the finite element analysis based on ANSYS, the unreasonable design of the feed mechanism is calculated and analyzed. So the design of the feed mechanism is adjusted. Finally, the motion and force analysis and strength check of the new scheme are carried out, and the reliability analysis of the improved scheme based on the finite element method based on Monte Carlo method is emphasized. It is concluded that under the condition of confidence of 95%, the stress values of the overturning arm, the spindle and the frame of the improved large steel feed mechanism are less than its yield strength, and the structure is reliable.
