4918 Study on Vibration Control Model and Behavior of Flexible Ladder Truck Subjected to Impulse Load
Details
A ladder truck with lift mechanism has played an important role in life-saving and fire-fighting. Although the quicker operation mechanism is requested for these demands, the lift operation generates a lot of vibration in the extending and retracting and ascending and descending motions. In this paper, the model of the ladder truck is proposed and two control methods for ladder are investigated. The first is the control of driving input wave. By selecting the appropriate input waveform, the vibration of the ladder is reduced. The second is optimal control for ladder subjected to impulse load. Performing the simulation studies, the effectiveness of control method is shown.
