Abstract: The simultaneous structural and control optimization of flexible linkage mechanisms based on noise attenuation is discussed. The thickness of the links and the parameters of control system are taken as the design variables simultaneously. The sum of the weighted structural mass and weighted controlled system energy terms is taken as the performance index. Optimization is carried out based on the modified constrained variable metric method. At last, a simulation is carried out to demonstrate the validation of the new method.
