Diagniosis of the Technical State of Complex Mechanical Systems

Abstract

The paper presents a model for prediction and diagnosis of technical state of complex mechanical systems based on the systems theory. In diagnosis studies is used a model that has only input and output parameters as a representation of the system function and behavior. In the paper the authors suggest a more complex model which contains command and control parameters as well. According to the prediction/diagnosis studies a model allows: mathematical expression of the process, determination of the parameter values for the independent inputs and the variable parameters, identification of both measurable and non-measurable parameters. Diagnosis prediction can be done for short, medium and long term. A very important problem remain: passing from the tribomodel to the tribosystem in order to diagnose the life time.
