【摘要】：高速旋轉(zhuǎn)機械廣泛應(yīng)用于醫(yī)療、石油化工、航空和動力工程等行業(yè),是許多現(xiàn)代化工業(yè)的關(guān)鍵設(shè)備。設(shè)備的正常運行,直接影響著人們的安全生產(chǎn)和企業(yè)的經(jīng)濟效益。旋轉(zhuǎn)機械在高速運轉(zhuǎn)過程時,機構(gòu)的一部分偏心質(zhì)量會產(chǎn)生不平衡力使機構(gòu)產(chǎn)生機械振動,損傷設(shè)備的可靠性和使用壽命。本文基于動平衡理論,設(shè)計了一種新型自動平衡調(diào)節(jié)裝置,運用于高速轉(zhuǎn)子的主動平衡工況,以調(diào)節(jié)旋轉(zhuǎn)機械的質(zhì)心位置,解決由于質(zhì)量偏心而引起的機械振動對系統(tǒng)的影響問題。本文以醫(yī)療旋轉(zhuǎn)機械恒溫振蕩器為研究對象,針對其運轉(zhuǎn)過程中產(chǎn)生動態(tài)不平衡現(xiàn)象,分析了它產(chǎn)生動態(tài)不平衡的原因,并設(shè)計了新型自動平衡方案。運用Cero、Solidworks等軟件建立恒溫振蕩器的三維模型,分析調(diào)節(jié)裝置的調(diào)節(jié)范圍,并對極限位置的狀態(tài)進行力學(xué)計算。本文運用ANSYS Workbench和ADAMS軟件對恒溫振蕩器自動平衡裝置進行靜力學(xué)分析和動力學(xué)分析,得到平衡塊處于不同角度時的振動頻率和振型圖。最后搭建實驗平臺,編寫觸屏操作界面,設(shè)計整機測試系統(tǒng)進行實驗分析。經(jīng)過平衡調(diào)節(jié)方案的詳細設(shè)計、制圖和生產(chǎn)制造搭建了實驗平臺并進行試驗,驗證設(shè)計的自動平衡方案的可行性。通過對新型恒溫振蕩器平衡調(diào)節(jié)裝置的建模、力學(xué)性能的分析、傳動方案的設(shè)計以及實驗平臺的搭建,測試結(jié)果表明本平衡方案能有效減小恒溫振蕩器的動不平衡產(chǎn)生的振動問題,對后續(xù)旋轉(zhuǎn)機械產(chǎn)品自平衡的研發(fā)具有一定的理論指導(dǎo)意義和參考價值。
[Abstract]:High speed rotating machinery is widely used in medical, petrochemical, aviation and power engineering industries. It is the key equipment of many modern industries. It has a direct impact on the safety of production and the economic benefits of enterprises. When rotating machinery is running at high speed, a part of eccentric mass of the mechanism will produce unbalanced force to make the mechanism produce mechanical vibration. Based on the theory of dynamic balance, a new type of automatic balancing device is designed to adjust the center of mass of rotating machinery under the active balancing condition of high speed rotor. The influence of mechanical vibration caused by mass eccentricity on the system is solved. In this paper, the thermostatic oscillator of medical rotating machinery is taken as the research object. The cause of dynamic imbalance is analyzed, and a new automatic balancing scheme is designed. The three-dimensional model of constant temperature oscillator is established by using Cero/ Solidworks software, and the adjustment range of regulating device is analyzed. In this paper, ANSYS Workbench and ADAMS software are used to analyze the statics and dynamics of the automatic balance device of the constant temperature oscillator. The vibration frequency and vibration pattern of the balance block at different angles are obtained. Finally, the experimental platform is built, the touch screen operation interface is compiled, and the testing system of the whole machine is designed for experimental analysis. After the detailed design of the balancing adjustment scheme, The experiment platform was set up and the experiment was carried out to verify the feasibility of the designed automatic balancing scheme. By modeling and analyzing the mechanical properties of the new thermostatic oscillator balance regulating device, The design of the transmission scheme and the construction of the experimental platform show that the proposed balancing scheme can effectively reduce the vibration problem caused by the dynamic unbalance of the thermostatic oscillator. It has certain theoretical guiding significance and reference value for the following research and development of self-balance of rotating machinery products.
