변위 입력 시스템에 대한 위상 최적설계

Generally, topology optimization deals with force input systems which is very common in structural analysis. And design sensitivity analysis(DSA) for those systems has been well established by many mathematicians and engineers. In general, the force input model works well for the general structural systems. Certain physical system, however, requires displacement input model, such as voltage input in electrostatic systems. This paper present the DSA for displacement input systems using the adjoint variable method(AVM). For design of the compliant mechanisms which are structural systems, the displacement input model has shown better performance than the force input model. The authors believe that the derived DSA equations in this research can be applied to the various physical systems, especially to the Microelectromechanical Systems(MEMS).
