【摘要】：球磨機(jī)作為一種磨粉設(shè)備,被廣泛應(yīng)用在多種行業(yè),并發(fā)揮著巨大的作用。球磨機(jī)屬高能耗設(shè)備,如何降低球磨機(jī)的能耗,提高球磨機(jī)的效率是當(dāng)前磨粉機(jī)的主要研究方向。因此,研制新型球磨機(jī),優(yōu)化球磨時(shí)的關(guān)鍵參數(shù),對(duì)球磨機(jī)的粉磨效率的提高具有重大的意義。 本文研究的對(duì)象是章動(dòng)球磨機(jī),它是一種利用章動(dòng)原理設(shè)計(jì)的新型磨機(jī),可用于物料的細(xì)磨、超細(xì)磨。在章動(dòng)球磨機(jī)處于運(yùn)行狀態(tài)時(shí),磨機(jī)腔體里面的磨料之間以及磨料與腔體內(nèi)壁之間會(huì)發(fā)生強(qiáng)烈的撞擊和摩擦,這種運(yùn)動(dòng)現(xiàn)象十分復(fù)雜。為了優(yōu)化球磨時(shí)的參數(shù),提高章動(dòng)球磨機(jī)的粉磨效率,就需要研究球料在腔體中的運(yùn)動(dòng)形態(tài)和規(guī)律。 為了模擬仿真球磨介質(zhì)在腔體中的運(yùn)動(dòng)形態(tài),本文采用ADAMS軟件來(lái)建立球磨機(jī)的虛擬樣機(jī),通過(guò)研究球磨介質(zhì)運(yùn)動(dòng)形態(tài)的途徑來(lái)優(yōu)化球磨機(jī)的關(guān)鍵設(shè)計(jì)參數(shù)。 論文首先介紹了本課題的來(lái)源與背景,以及國(guó)內(nèi)外對(duì)球磨機(jī)的最新研究情況。之后給出了章動(dòng)球磨機(jī)的結(jié)構(gòu)組成及其工作原理,描述了基于ADAMS軟件的球磨機(jī)虛擬樣機(jī)系統(tǒng)建模的具體方法,詳細(xì)分析了各個(gè)仿真參數(shù)的選擇。然后分別仿真了單個(gè)鋼球和滿載時(shí)鋼球的運(yùn)動(dòng)形態(tài),以及球磨機(jī)轉(zhuǎn)速和章動(dòng)角的大小對(duì)鋼球運(yùn)動(dòng)形態(tài)的影響。并利用SolidWorks Motion軟件,再次建立了球磨機(jī)虛擬樣機(jī)模型仿真對(duì)比的方法,驗(yàn)證了ADAMS虛擬樣機(jī)模型建立的正確性。在此基礎(chǔ)上,對(duì)章動(dòng)球磨機(jī)的主要零部件主軸和軸承進(jìn)行了疲勞強(qiáng)度計(jì)算和壽命分析,為章動(dòng)球磨機(jī)的設(shè)計(jì)提供依據(jù)。最后,對(duì)設(shè)計(jì)的章動(dòng)球磨機(jī)試驗(yàn)樣機(jī)的進(jìn)行了簡(jiǎn)單地試驗(yàn)研究。 總之,通過(guò)對(duì)章動(dòng)球磨機(jī)的動(dòng)力學(xué)分析,對(duì)改進(jìn)章動(dòng)球磨機(jī)的設(shè)計(jì)提出了優(yōu)化建議。通過(guò)將來(lái)的進(jìn)一步研究,對(duì)改善章動(dòng)球磨機(jī)這種新型的磨粉設(shè)備具有重要意義。
[Abstract]:Ball mill, as a kind of grinding equipment, is widely used in many industries and plays a great role. The ball mill is a kind of high energy consumption equipment, how to reduce the energy consumption of ball mill, Improving the efficiency of ball mill is the main research direction of present mill. Therefore, it is of great significance to develop a new type ball mill and optimize the key parameters of ball mill to improve the grinding efficiency of ball mill. The object of study in this paper is nutation ball mill, which is a new mill designed by nutation principle, which can be used for fine grinding and ultra-fine grinding of materials. In order to optimize the parameters of ball mill and improve the grinding efficiency of nutation ball mill, there will be strong impact and friction between abrasives inside the grinding chamber and between the abrasive and the inner wall of the cavity, which is very complicated. It is necessary to study the motion pattern and law of the ball material in the cavity. In order to simulate the motion pattern of ball milling medium in the cavity, the virtual prototype of ball mill is established by ADAMS software, and the key design parameters of ball mill are optimized by studying the motion pattern of ball mill medium. This paper first introduces the source and background of this topic, and the latest research situation of ball mill at home and abroad. Then, the structure and working principle of nutation ball mill are given. The modeling method of ball mill virtual prototype system based on ADAMS software is described, and the selection of simulation parameters is analyzed in detail. The effect of rotational speed and nutation angle of ball mill on ball motion pattern is also discussed. The simulation method of virtual prototype model of ball mill is established by using SolidWorks Motion software. The correctness of the ADAMS virtual prototype model is verified. On this basis, the fatigue strength calculation and life analysis of the main parts of the nutation ball mill spindle and bearing are carried out, which provides the basis for the design of the nutation ball mill. The test prototype of nutation ball mill is studied simply. In a word, through the dynamic analysis of nutation ball mill, the optimization suggestion is put forward for improving the design of nutation ball mill. Through further research in the future, it is of great significance to improve the nutation ball mill, a new type of grinding equipment.
