Abstract
Permanent magnet elastomer particles using in this study are spherical particles that are magnetized by dispersing neodymium fine particles in an elastomer. Damper force of a separated dual-chamber single-rod type damper using permanent magnet elastomer particles was investigated experimentally and numerically. Behavior of permanent magnet elastomer particles inside the damper was simulated using the discrete particle method. When a magnetic field is applied, the damper force of a particle damper using permanent magnet elastomer particles increases. Because the Young's modulus of the permanent magnet elastomer increases with the application of a magnetic field, and the normal compressive force increases due to the magnetic interaction force acting between particles, resulting in an increase in the frictional force.
