摘要：
Our previous study showed the effect of pre-tension onto oscillation at the top of a ladder in raising and lowering processes on turntable ladders when steel wire ropes are added to ladder handrails. However, the oscillation was not switched off quickly. To quickly extinguish oscillation, we use steel ropes and a hydraulic system that is available on the truck to control the vibration. Based on the available multibody dynamic system and motion equation of the ladder, the group minimizes the number of variables in the motion equation and linearizes it. Thereafter, the vibration of the system is controlled and simulated by Matlab-Simulink software. This study presents a new method to control the ladder vibration on the turntable ladder.
