【摘要】：液壓圓錐破碎機(jī)作為礦山、化工、冶金、水泥等重工業(yè)重要的生產(chǎn)設(shè)備,在生產(chǎn)領(lǐng)域所發(fā)揮的作用也越來越突出。破碎機(jī)的工作性能直接影響企業(yè)的生產(chǎn)效益。但是我國設(shè)計(jì)的破碎機(jī)存在噪聲大、振動突出、破碎效率低、關(guān)鍵零部件設(shè)計(jì)不合理等結(jié)構(gòu)問題。所以對破碎機(jī)關(guān)鍵零部件進(jìn)行理論分析具有十分重要的實(shí)際意義。本文以PLM1500I液壓圓錐破碎機(jī)作為目標(biāo)對象進(jìn)行具體的理論研究,本文主要做了如下研究:(1)對層壓破碎理論進(jìn)行研究并計(jì)算破碎力。對定錐襯板進(jìn)行動態(tài)特性分析,分析定錐襯板的危險部位,驗(yàn)證是否滿足破碎機(jī)工作要求。然后對定錐襯板進(jìn)行模態(tài)分析,提取定錐襯板的前6階模態(tài)。防止破碎機(jī)的固有頻率與定錐襯板的固有頻率相近造成共振而降低安全性。(2)對圓柱滾子軸承進(jìn)行動態(tài)特性分析。諧響應(yīng)分析首先以模態(tài)分析為基礎(chǔ),在模態(tài)分析的基礎(chǔ)上施加載荷進(jìn)行諧響應(yīng)分析,得出圓柱滾子軸承在承受一定載荷條件下的結(jié)構(gòu)響應(yīng)。防止圓柱滾子軸承在承受周期性載荷條件下發(fā)生較大變形而降低破碎機(jī)使用壽命。(3)對傳動系統(tǒng)中的連接件及定錐襯板進(jìn)行疲勞分析,利用ANSYS-Workbench的疲勞分析模塊,得出零件的主要壽命及安全系數(shù)云圖。疲勞分析對破碎機(jī)的設(shè)計(jì)及優(yōu)化具有一定的參考意義。(4)對定錐襯板提出了優(yōu)化設(shè)計(jì)方案,將定錐襯板優(yōu)化前后的機(jī)械性能進(jìn)行對比。通過優(yōu)化提高定錐襯板的使用性能,同時提高破碎機(jī)的耐用性。以層壓破碎理論為基礎(chǔ),結(jié)合ANSYS-Workbench仿真軟件對破碎機(jī)關(guān)鍵零部件進(jìn)行有限元分析,減少工廠設(shè)計(jì)時間同時降低設(shè)計(jì)成本,這是本文最大的創(chuàng)新點(diǎn)。通過對破碎機(jī)關(guān)鍵零部件進(jìn)行有限元分析,我們得出定錐襯板的設(shè)計(jì)及使用符合要求且不會發(fā)生共振想象。同時對定錐襯板結(jié)構(gòu)進(jìn)行了優(yōu)化,得出優(yōu)化后的性能更為優(yōu)越。圓柱滾子軸承在承受一定周期性載荷條件下不會產(chǎn)生較大變形,軸承的選擇符合破碎機(jī)的設(shè)計(jì)要求。連接件作為傳動系統(tǒng)中重要的零件,疲勞特性符合破碎機(jī)工作要求。
[Abstract]:Hydraulic cone crusher, as an important production equipment in heavy industry such as mine, chemical industry, metallurgy, cement and so on, plays a more and more important role in the field of production. The working performance of the crusher has a direct impact on the production efficiency of the enterprise. But the crusher designed in our country has some structural problems, such as high noise, outstanding vibration, low crushing efficiency and unreasonable design of key parts. So the theoretical analysis of the key parts of the crusher has very important practical significance. This paper takes the PLM1500I hydraulic cone crusher as the target object to carry on the concrete theoretical research, this paper mainly has done the following research: (1) carries on the research to the laminate crushing theory and calculates the breaking force. The dynamic characteristics of the fixed cone liner are analyzed, the dangerous parts of the fixed cone liner are analyzed, and the working requirements of the crusher are verified. Then the first six modes of the fixed cone liner are extracted by modal analysis. The natural frequency of the crusher and the natural frequency of the fixed cone liner are similar to those of the fixed cone liner to prevent resonance and reduce the safety. (2) the dynamic characteristics of the cylindrical roller bearing are analyzed. On the basis of modal analysis, harmonic response analysis is carried out on the basis of modal analysis, and the structural response of cylindrical roller bearings under certain loading conditions is obtained. The cylindrical roller bearing is prevented from deforming and reducing the service life of crusher under the condition of periodic load. (3) the fatigue analysis of the connecting parts and the fixed cone lining plate in the transmission system is carried out, and the fatigue analysis module of ANSYS-Workbench is used. The main life and safety factor cloud diagram of the parts are obtained. Fatigue analysis has certain reference significance to the design and optimization of crusher. (4) the optimum design scheme of fixed cone lining plate is put forward, and the mechanical properties of fixed cone liner plate before and after optimization are compared. Through optimization, the performance of fixed cone liner is improved and the durability of crusher is improved at the same time. Based on the theory of laminate crushing, the finite element analysis of the key parts of the crusher is carried out with ANSYS-Workbench simulation software to reduce the design time and design cost. This is the biggest innovation of this paper. Through the finite element analysis of the key parts of the crusher, we get the conclusion that the design and use of the fixed cone liner meet the requirements and no resonance imagination will occur. At the same time, the structure of fixed cone lining plate is optimized, and the optimized performance is more superior. Cylindrical roller bearing does not produce large deformation under a certain periodic load, and the selection of bearing accords with the design requirements of crusher. As an important part of the transmission system, the fatigue characteristic of the connector meets the working requirements of the crusher.
