First, the theory of fretting wear and studies on fretting fatigue were introduced and the parametric method was used in the process of creating the model of dovetail joints in UG software. The elastic contact problem is analyzed in finite element method and is used to the parameters' distribution and contact stress of the joint are obtained on the base of ANSYS code. With the effect factor of load frequency, the prediction method of fretting fatigue life of dovetail joint under low and high/low cycle complex load is proposed. The proposed model and the approach were verified by experiments.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
