The optimal design of symmetrical Langevin transducers using multiobjective evolutionary algorithms (MOEAs) is studied. The design problem is formulated as a constrained multiobjective optimization problem (MOP) involving continuous design variables (dimensions of the transducer) and discrete design variables (the number of piezoelectric rings and material types). The maximum vibration amplitude and...
Structure synthesis method for reconfigurable mechanism based on genetic optimization algorithm is proposed in this paper. Main characteristics of this method include: (1) POC matrix of the mechanism corresponding to different motion stage of the reconfigurable mechanism is used as the objective function. (2) design variables are determined based on the influence of three basic topological structure...
Buerjin power grid of Xinjiang province in China is an alone hydraulic-wind power mutual compensation system, which is composed of two hydraulic generators with capacity of 2000 KW and one with 2500 KW and seven wind generators with capacity of 150 KW, the wind power capacity account for almost 13.0 percent of total power system capacity. In order to study the optimal capacity scheme of wind power...
