According to the trend of giving high quality to construction machinery, improvement of riding comfort has recently been highlighted. However cab system, which is mounted on supporting structure by rubber, has inevitable vibration problem in low frequency range below 20 Hz. Especially its natural rolling mode about 10 Hz hurts riding comfort of operator, and this mode has been required to reduce as possible. This paper deals with a modal synthesis of troublesome rolling vibration, and a application of TMD (Tuned Mass Damper), designed by the information of system identification.
