磨合过程摩擦振动混沌吸引子演变规律

在CFT-I型试验机上进行摩擦副磨合试验，应用混沌理论研究摩擦振动吸引子，探讨磨合过程中摩擦振动混沌吸引子的演变规律。结果表明，摩擦振动吸引子在相空间一定区域内具有特定层次结构且永不封闭轨迹。摩擦振动具有混沌行为的基本特征；随磨损过程的进行，摩擦振动混沌吸引子逐渐收缩并趋于稳定，混沌吸引子变化能反映摩擦副从磨合磨损到稳定磨损状态变化；摩擦振动混沌吸引子体积变化可用于摩擦副的磨合磨损状态预测与识别。

Evolvement rule of frictional vibration chaos attractor in running-in process

Wear tests were conducted on the CFT-Ⅰtester. The frictional vibration signals were extracted and its attractors were researched by using the chaos theory. The variation of frictional vibration chaos attractors in the wear process was discussed. It was shown that the frictional vibration is characterized by chaos, and its chaos attractor has a specific hierarchy and is a never closed trajectory in phase space. The chaos attractor of frictional vibration displayed convergence trend at the beginning of running-in stage and tended to be in stable state as the wear process went on. The chaos attractor depicts the wear state variation from running-in wear to stable wear. Therefore, the wear state of a friction pair can be predicted and identified by observing the change of chaos attractor volume of frictional vibration signals.

Abstract

Wear tests were conducted on the CFT-Ⅰtester. The frictional vibration signals were extracted and its attractors were researched by using the chaos theory. The variation of frictional vibration chaos attractors in the wear process was discussed. It was shown that the frictional vibration is characterized by chaos, and its chaos attractor has a specific hierarchy and is a never closed trajectory in phase space. The chaos attractor of frictional vibration displayed convergence trend at the beginning of running-in stage and tended to be in stable state as the wear process went on. The chaos attractor depicts the wear state variation from running-in wear to stable wear. Therefore, the wear state of a friction pair can be predicted and identified by observing the change of chaos attractor volume of frictional vibration signals.
