Springs are used for various purposes, particularly for vibration control and the removal of machines. However, the use of a spring generates a high amplitude at the resonance point; therefore, it is difficult to suppress vibrations from all frequency bands. To solve this issue, a variable rate spring is developed, which is a magnetic spring. This variable rate spring can change its spring constant. An experiment is carried out by placing compression and magnetic springs along the same axis to miniaturize the experimental device. Basically, the natural frequency of the vibration system fluctuates with changes in the spring constant. As a result, the problem can effectively be resolved by changing the resonance point and suppressing the vibration. The variable rate spring consists of magnetic and compression springs; the utility of the spring is verified by an experiment and a simulation.

“…A permanent magnet can generate a strong magnetic force, and electric power is not necessary; however, it is difficult to control. Thus, if a permanent magnet is applied to a variable rate spring, the resulting spring could have a very large spring constant [1][2][3][4][5][6].…”

Recently, linear oscillatory actuators have been used in a wide range of applications. In particular, small linear oscillatory actuators are expected to be used in haptic devices by being extended to provide multi-degree-of-freedom motion with arbitrary acceleration. In this paper, we propose a compact two-DOF oscillatory actuator that can move in various directions on a plane. The static and dynamic characteristics of the actuator are determined by the 3D finite element method. The effectiveness of this method is shown through a comparison of the measured results with the experimental results from a prototype.
