In this paper, a strongly coupled method for interaction of rigid body, incompressible viscous fluid and electrostatic field is developed. The present method is composed of monolithic and partitioned methods. The former solves structure fluid interaction and the later solves interaction of electrostatic field and the other fields. The difference between the present method and conventional method is the introduction of the iterative solution procedure in the partitioned method. To demonstrate the fundamental performances of the present method, it is applied to simulate a micro membrane actuated by electrostatic force situated in air. The present result agrees well with the theoretical solution when the displacement of the rigid body is small. We also comfirm that the iterative solution procedure makes the present method to be the strongly coupled method through the numerical example.
