자성유체가 구동원으로 사용된 엑츄에이터에 대한 실험적 연구

The basic characteristics of actuator are a displacement, velocity and force of driving body. This paper describes the force among that of actuator. A length and diameter of straight tube are selected condition that can stabilize the magnetic fluid plug in the U-type tube. Load cell measures a force and response of magnetic fluid for a supplied voltage. A force that is generated by magnetic fluid in the straight tube have the magnetic body force, potential energy of a cluster and so on.
