发布时间：2019-06-06 13:12
【摘要】：利用变步长迭代算法在Matlab平台上对微轴承的修正模型进行仿真模拟。通过传统连续模型、一阶滑移修正及Wu新滑移修正模型的对比发现,在最小气膜间隙处各滑移修正模型得到的参量远低于连续模型的结果。而且当气膜间隙小于1μm时,各模型之间的结果偏差随气膜间隙的减小而迅速放大,连续模型已不适于此条件下的特性分析,必须考虑滑移修正效应的影响,以便得到较精确的相关电子设备中的参量特性。
[Abstract]:The modified model of micro bearing is simulated on Matlab platform by using variable step size iterative algorithm. By comparing the traditional continuous model, the first-order slip correction model and the Wu new slip correction model, it is found that the parameters obtained by each slip correction model at the minimum film gap are much lower than those obtained by the continuous model. When the gas film gap is less than 1 渭 m, the result deviation between the models is enlarged rapidly with the decrease of the gas film gap. The continuous model is no longer suitable for the characteristic analysis under this condition, and the influence of slip correction effect must be taken into account. In order to obtain more accurate parameter characteristics in related electronic equipment.
