The dynamic behavior of a damped vibration system containing thixotropic materials is experimentally investigated. Thixotropic materials are substance which liquefy when stirred or shaken and return to the hardened state upon standing. We construct a device to evaluate vibration of a washing machine containing thixotropic materials and vibration tests are performed using the device with a rotating unbalance turning in inner tub. Normally, the outer tub of a washing machine is suspended by the supporting bars with damping mechanism. We proposed the new damping mechanism with thixotropic materials. Transmitted force from outer tub to outer housing is measured. The tests indicated that optimum shape (thickness and diameter) of piston changes when the consistency of thixotropic material changes.
