磁力と攪拌を用いた減衰に関する研究

抄録

Dampers are often used in vibration control and isolation systems for machines and structures. In this study, damping efficiency induced by stirring granular materials was investigated to develop stirring type dampers. Compared to oil dampers, which are currently the mainstream, this type of damper is superior in terms of application to high-temperature environments and ease of maintenance. However, there is still room for further consideration on structure to obtain higher stirring resistance. In this study, we attempted to increase the stirring torque by enclosing magnetic particles and generating a magnetic field in the container. As a result, it was confirmed that the stirring torque was increased by the magnetic field.
