Abstract
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. Performing the numerical simulations taking the dimensions of the model and the modification of the input motion as parameters, the physical meaning of the dynamic behavior at the time of the lift operation is discussed. Moreover, the optimal control method for minimizing the vibration of a ladder is discussed.
