【摘要】：國產(chǎn)大型空分設(shè)備運行可靠性差,連續(xù)運轉(zhuǎn)周期短,設(shè)備故障率高,空氣分離類成套裝備運轉(zhuǎn)穩(wěn)定性研究,已經(jīng)成為國內(nèi)迫切需要解決的科學(xué)問題。以某大型空分機組滑動軸承支撐軸系為研究對象,得到軸承油膜系統(tǒng)勞斯陣列;勞斯陣列第一列元素都為正值,運用勞斯穩(wěn)定性判據(jù)得到軸承油膜系統(tǒng)穩(wěn)定;運用傳遞矩陣原理,借助MATLAB軟件求解矩陣,計算出軸系各軸承的標高與載荷值;依據(jù)軸系在聯(lián)軸器處彎矩和剪力為零的原則,得到軸系安裝揚度曲線;軸系安裝揚度曲線為一條光順的曲線。該研究為大型多跨、多支撐軸系穩(wěn)定性研究提供了重要參考和工程依據(jù)。
[Abstract]:The research on the operation stability of domestic large air separation equipment with low reliability, short continuous operation period, high failure rate and complete sets of air separation equipment has become an urgent scientific problem to be solved in China. Taking the bearing supporting shafting system of a large air separation unit as the research object, the oil film system Ros array is obtained, and the first series of elements of the Ross array are all positive, and the stability of the bearing oil film system is obtained by using the Rouse stability criterion. Based on the transfer matrix principle and the MATLAB software to solve the matrix, the elevation and load values of each bearing of the shaft system are calculated, and according to the principle of zero bending moment and shear force at the shaft coupling, the installation lifting curve of the shaft system is obtained. The shafting installation lift curve is a smooth curve. This study provides an important reference and engineering basis for the study of the stability of large multi-span and multi-braced shafting.
