Bi-Level Design Optimization of the Hatch Door Mechanism

Abstract:

Optimization model and solution method are developed in the present paper to improve the design of the hatch door mechanism of a regional airliner. The real motion trajectory of the hatch door normally has deviations from the ideal trajectory due to existence of machining errors. In order to decrease such deviations, a bi-level optimization model is developed for the design of the size tolerance limits of the key parts. The design objective is to minimize the extremum deviation of the trajectory of the objective point of the hatch door. The extremum deviation is obtained by solution of the inner-level size optimization problem for the fixed size tolerance limits. The optimization models for motion control of the hatch door mechanism are solved by the response surface method.
