Pattern formation Phenomena due to time delay often occur in contact rotating system. In previous study, we have been established a stability analysis method based on the existence condition in stable and unstable boundary not only in a single-DOF system but also in a multi-DOF system which all time delays is same. And, last year's report showed the possibility theoretically to apply to the stability analysis method for a system including difference time delay. In this report, we verify the availability experimentally to apply to the stability analysis method for a system including difference time delay and compare experimental results with theoretical ones of a system including difference time delay. In addition, we confirm the validity of dynamic absorbers for a system including difference time delay. As an example, we take 4 Rolls 3-DOF system that two viscoelasticity rolls rotate while contacting directly.
