摘　　要：鉴于微载荷含油轴承性能研究中摩擦稳定性的重要性,对含油轴承摩擦学进行了混沌分析,得到了判别稳定性的条件.条件分为:无阻尼、无驱动情况下系统处于完全黏着弹性状态;阻尼加入摩擦力影响;驱动加入外部力影响.充分润滑的微载荷摩擦混沌现象表现为杂乱无章的速度与加速度关系.随着固体接触和固体摩擦成分的增加,速度与加速度关系相图表现出有规律的渐近稳定状态.The chaos analysis is performed for porous bearing because of the importance of friction stability.The stable discriminated condition is obtained.The conditions include that：total adhesive elasticity is simulated without damp and drive;damp carries a friction affect;drive carries an external force affect.Under linearization friction system and random function input,the chaos performance of micro-load porous bearing of rich lubricant shows complex unstable state on the phase diagram of speed-acceleration. With the increase of solid contact and solid friction composition, the phase diagram shows to tend to be stable.
