Reliability and Optimization Design, taking fuzzy reliability as well as all other conditions as design constraints, circumscribes feasible design field in design space and then explores the optimal design scheme in this feasible field with some method according to design objectives, which can guarantee the reliability, feasibility and optimality of design result.
The optimal design approach for structual parameters of the active magnetic bearings is shown. The mathematical model of the bearings is established. By using the penalty function method, the combination of design parameters can be optimized.
The results are helpful for the optimal design of the generator and the optimal control of exciting-winding.
Different topics are involved in the optimal design of coating-based systems.
Three flexibility problems, viz., the flexibility of a technical system of given structure, structural flexibility of a technical system, and the optimal design guaranteeing the flexibility of a technical system, are studied.
The optimal design of the real complex system (whose nature is stochastic) is determined from a mathematic model of an ideal complex system.
Using this method makes it possible to substantiate the choice of the optimal design of contact units in cascade pneumatic classifiers for various technological conditions.
