基于变步长迭代算法的微轴承参量特性研究
Study on micro bearing parameter characteristics simulated with variable step size iterative algorithm
摘要
Abstract
The variable step size iterative algorithm is used to simulate the modification model of the micro bearing in Matlab platform.It is found by comparison with the traditional continuum model,first-order slip correction model and Wu new slip model that the parameters obtained by all the slip correction models at minimum gas film clearance are far below the results got by the continuum model.When the gas film clearance is less than 1 μm,the deviation of results from each model increases rapidly with reduction of the gas film clearance.It means that the continuum model is not suitable for characteristic analysis under this condition.That's why the influence of slip correction effects must be considered,so as to achieve accurate parametric characteristics of aerostatic bearing in the related electronic equipment.关键词
