摘要: 轴承的动特性系数与轴颈在轴承中的位置有关。对于给定工况的转子-轴承系统,必须先求出轴颈的平衡位置,然后再解得轴承动力特性系数。用Newton法迭代求轴颈平衡位置,轴承的动特性系数已在获得轴颈平衡位置的同时求得,无需额外增加求解Reynolds方程的次数。

Abstract: The dynamic coefficients of oil-lubricated journal bearings depend on the journal position in a bearing. It is necessary to search journal balance position befor calculating the dynamic coefficients. The Newton iterative method is used to find the journal balance position. The dynamic coefficients are obtained simultanneously with the journal balance position and no extra solutions of Reynolds equations are needed.
