Abstract
A machine with the lift mechanism for high lift work often generates a vibration at the lift operation. This paper describes the simulation analysis of the dynamic behavior of telescopic mechanism which is one of the lift mechanism of a machine for high lift work. We make the dynamic analytical model of the two-step lift mechanism composing of elastic bodies. An equation of motion is derived using a differential alegebraic equation (DAE). the preliminaray in vestigation on vibration control is performed for a operation so as to operate it easily and safty. As a result, it become clear that the velocity of the telescopic mechanism have much affect on the generation of vibration.
