Feasibility Study on Ungrounded Pulling Force Display Using Electromagnetic Force of Solenoid

This paper models and simulates a solenoid-based force presentation device and presents the feasibility of pulling presentation. A weight is attached to the end of the solenoid plunger, and the other is connected to a spring. When the solenoid is activated, the weight is attracted to the solenoid, and when the current is cut off, the weight is returned to its original position by the spring. By properly designing the current in the coil, the motion of this weight can be made asymmetric acceleration motion, and pulling force can be presented. In order to confirm this feasibility, first, the proposed system is modeled. Next, the current was adjusted so that the solenoid's pulling force could be expressed as a function of the current in the coil. The result of the simulation is that the generation of asymmetric acceleration motion of the weights was confirmed. Therefore, the feasibility of the proposed method was confirmed.
