Abstract
A ladder of the ladder truck with the lift mechanism often generates a vibration at the time of the lift operation. This paper describes the simulation analysis of the dynamic behavior of extension motion and elevation motion which are one of the lift mechanism in order to make clear its vibration phenomena. We make the dynamic analytical model composed of 2 sections ladder using Multibody Dynamics. An equation of motion is derived using differential algebraic equation (DAE). We investigate the validity of our proposed simulation analytical method by comparing the simulation results with the experimental ones.
