Proposed of novel linear oscillating actuator's structure using topology optimization

This paper proposes a magnetic structure optimization method of a linear oscillating actuator (LOA). The higher-efficient magnetic structure is necessary for reduction in size and weight of a LOA. In a conventional optimization method using a genetic algorithm (GA), it depends on a initial shape har...

Summary:This paper proposes a magnetic structure optimization method of a linear oscillating actuator (LOA). The higher-efficient magnetic structure is necessary for reduction in size and weight of a LOA. In a conventional optimization method using a genetic algorithm (GA), it depends on a initial shape hard, and can't get a novel magnetic structure. In this paper, we propose the topology optimization method which does not need the initial shape. The unguessed magnetic structure with magnetization direction and ferromagnetic shape is computed using proposed method.
