摘要
采用了无网格法来求解滑径向动轴承的无量纲油膜压力分布。此无网格法是基于径向基函数插值的配点法。在构造径向基插值时添入了线性多项式,避免了奇异性和提高了精度。将此方法计算出的结果和经典结果进行了比较,验证了此方法的可行性。并对某一给定参数的滑动轴承的油膜压力和承载能力进行了计算。
A meshfree method is used to calculate the dimensionless distributed pressure of journal bearing. This method is based on collocation point of radial basis functions. This paper uses the radial point interpolation with a linear polynomial to avoid the singularity and improve the accuracy. Then the load capacity of the journal bearing is calculted and the results are compared with classical ones, which so that its feasibility is verified. The pressure distribution and load capacity of the journal bearing with defined parameters are obtained by this method.
