0399-管磨機的總體和結(jié)構(gòu)設(shè)計,管磨機,總體,整體,以及,結(jié)構(gòu)設(shè)計 管磨機動態(tài)特性及系統(tǒng)的測試分析 摘要：磨機是發(fā)電、選礦、化工和建材等重工業(yè)領(lǐng)域中最廣泛采用的粉磨機械，其主要機件有傳動裝置、支承裝置、回轉(zhuǎn)筒體。 本文建立了邊緣傳動式磨機系統(tǒng)的“小齒輪——傳動軸——減速機大齒輪”橫向振動的模型，分析計算了系統(tǒng)橫向振動的動態(tài)特性，對系統(tǒng)的載荷進行了測試分析，同時，還建立了磨機系統(tǒng)的扭轉(zhuǎn)振動模型，利用遞推計算法對系統(tǒng)進行了扭轉(zhuǎn)振動動態(tài)特性分析，驗證了遞推計算法的通用性。最后，對Φ2.6×13m的磨機系統(tǒng)進行了動態(tài)特性的實例分析。 研究邊緣傳動磨機系統(tǒng)的動態(tài)特性，對避免由于激勵頻率接近或等于系統(tǒng)的固有頻率而導致共振及設(shè)備的失效，預(yù)測系統(tǒng)在可能激勵下的響應(yīng)特性，優(yōu)化系統(tǒng)結(jié)構(gòu)等等都具有很重要的意義。 用傳遞矩陣法及通用計算程序可以簡便地分析邊緣傳動磨機系統(tǒng)橫向振動的固有特性，以及計算不同激勵情況下系統(tǒng)的響應(yīng)，為研究邊緣傳動磨機系統(tǒng)橫向振動的動態(tài)特性提供了一個方便有效的方法。 邊緣傳動磨機系統(tǒng)是一個模態(tài)偶合較緊的系統(tǒng)，因此，在磨機系統(tǒng)的設(shè)計、運行中，應(yīng)注意使激勵頻率避開系統(tǒng)的固有頻率，以免發(fā)生設(shè)備的早期失效。 邊緣傳動式磨機系統(tǒng)的傳動軸的設(shè)計是合理的。 系統(tǒng)阻尼對系統(tǒng)的動態(tài)特性影響很大，是系統(tǒng)的一個重要性能參數(shù)。 邊緣傳動磨機系統(tǒng)，可以通過實測低速軸的扭矩來確定系統(tǒng)中減速機的負載狀況。 關(guān)鍵詞：振動 載荷 響應(yīng)特性 扭矩 Tube Mill and testing of the system Dynamic Analysis Abstract：Tube Mill is important rules that Research for Dynamic characteristics of the mill system of single -pinion drives in operation to prevent damage from the resonance between fix frequency and bestir frequency In this paper , the pattern of Pinion---Drive shaft---Decelerator gear vertical vibration in the mill system of single -pinion drives is established . Dynamic characteristics of vertical vibration is analyzed and calculated ,and its excitation loads are tested Simultaneously , the model of torsion vibration in system is also established, its dynamic characteristics is analyzed by using recurrence calculus method , thus , this methods current is verified . Finally, the paper studied the dynamic characteristics of 2.6x13m mill system. Mill system of single - pinion drives is lighten, so the design and run of mill system, bestir frequency must avoid inhesion.The design of drive shaft is rational in mill system of single - pinion drives. It is very large that damp of system effect to dynamic characteristics, so the damp is a important parameter. Load of gear box can be decided by measuring of low speed shaft contort. In mill system of single - pinion drives. Key words：vibration response characteristics load torque
