1迷宫密封结构对泄漏量和轴系临界转速影响分析研究显示文摘运用数值方法对转子-轴承-密封系统动力学模型求解,对3种密封间隙、8种密封直径、8种压差、8种入口损失率和21种密封长度对泄漏量和临界转速的影响进行研究;通过密封结构对轴系临界转速影响规律进行研究,对比分析了有、无密封力作用下转子-轴承-密封系统对临界转速影响。研究结果表明:通过与DYNLAB程序、TASCFlow程序的结果对比分析,该数学模型能较好的模拟计算泄漏量和转子系统临界转速;通过对泄漏量影响规律研究,得出泄漏量随着密封间隙、密封直径和密封长度做增大而增大,泄漏量随压差和入口损失率的增大而减小。通过对临界转速影响规律研究,得到考虑密封会提高临界转速,密封长度的变化对临界转速的影响最大、密封间隙的变化对临界转速影响最小。马文生 陈照波 焦映厚 R G Kirk 2013振动工程学报2013,26,6:12
2转速数对滑动轴承动力学系数影响研究显示文摘建立了滑动轴承的基于短轴承非线性油膜力模型,通过转速对轴承动力学特性的影响研究,得到了偏心率、最小油膜厚度、最大油膜压力、摩擦功耗、温升、临界轴颈质量、刚度系数、阻尼系数、二维和三维油膜压力的影响因素研究;在对三维油膜压力分析时发现转速存在一个临界值,当转速低于这个临界值时,转速对最大油膜压力影响较大,当转速高于这个临界值时,转速对最大油膜压力影响不大。马文生 陈照波 焦映厚 Kirk R G 2014振动与冲击2014,33,5:11
3偏心率和转速对迷宫密封力和动力学参数影响分析研究显示文摘通过数值方法和商用CFD(计算流体动力学)软件对密封-转子系统进行建模和求解,研究了5种偏心率和5种转速下的计算机求解时间、流场压力分布、密封力的变化情况,并对泄漏量影响分析和迷宫密封动力学参数影响进行分析研究。研究结果表明:该方法能较好地模拟计算迷宫密封泄漏量和动力学参数,得到腔室压力随着偏心率增大而增大,密封切向力随着偏心率、转速的增大而增大,密封径向力随着偏心率、转速的增大而负向增大;通过密封长度、密封间隙、密封压差对泄漏量影响计算,三者变化率分别为6.62%,65.21%和69.97%,表明密封间隙和压差变化是影响泄漏量变化的重要影响因素;通过密封压差和密封长度对动力学参数影响分析,得出增大密封压差和密封长度不利于系统稳定、增大密封间隙会使得系统趋于稳定。马文生 陈照波 焦映厚 R G Kirk 2012振动工程学报2012,25,3:7
