Uçak kanopisi hareketlendirme mekanizmasinin boyutsal optimizasyonu

This thesis presents a method for generating suitable mechanism for a defined problem step by step. The problem dealt with is finding an optimum solution for opening an aircraft canopy providing also locking in the same solution. For the objective, two types of mechanisms are used. Firstly, a Stephenson III type six-bar linkage is synthesized, then it is modified to geared seven-bar to get more movement capability. This work includes both synthesis with motion generation and optimization with genetic algorithm. 10 poses are defined to be approximated by the motion, and an original code of genetic algorithm is created to be used for dimensional optimization of the mechanism. Many trials are applied for both six-bar and geared seven-bar linkages, and a satisfying solution is obtained by the geared seven-bar mechanism finally. The mechanism described in this thesis is designed for an aircraft canopy actuation, but the methods can be used and applied for different purposes and fields.
