Research on maintenance decision making based on vibration data

摘要：

　　Based on vibration data monitoring, by factors including vibration intensity and fault probability, system health state can be characterized, factors weight coefficients can be calculated, and health state function can be established, which are formal representation of system health state.Health state is divided into five levels, each level obtains its membership function by analyzing the characteristic of each factor.Using system health state as input of maintenance decision-making, predictive maintenance decision can be established.Good maintenance decision can efficiently reduce the maintenance cost and improve system availability.In this thesis,research on function expression of system health state based on vibration data was conducted.Then, using opportunity-group maintenance function based on system health state, maintenance decision was made.
