Topology Optimization of Pick-up Actuator of CD-ROM for Vibration Reduction
위상 최적 설계를 통한 CD-ROM 광 픽업 액추에이터의 진동 저감
- Published : 2000.06.22
Abstract
The topology optimization of electromagnetic systems is investigated and the TOPEM (Topology Optimization for Electromagnetic Systems) is developed using the finite element method (FEM). The design sensitivity equation for topology optimization is derived using the adjoint variable method. The proposed method is validated by applying it to the topology optimizations of a C-core actuator and an optical pickup actuator.
