This study investigates optimal arrangement of Active Wheel Dampers (AWDs) based on vibration control performance and static deflection amount when multiple AWDs are mounted on sprayer beam modeled as a cantilever beam. Static deflection amount is evaluated as the sum of static deflection amount depending on the gravity affecting on the cantilever beam and static deflection amount depending on the masses of AWDs. The peak gains of primary mode to fourth modes are evaluated from the magnitude of deflection towards disturbance of various frequency at each AWDs mounted position. And the sum of the peak gains that primary mode to fourth modes is normalized by the gain in the static state when the frequency of disturbance is zero. We defined the normalized gain as the magnitude of deflection towards disturbance. The magnitude of the amplitude of output torque of AWDs is calculated, and vibration control performance is evaluated by the magnitude of deflection towards disturbance and the magnitude of the amplitude of output torque of AWDs. Static deflection amount and vibration control performance when multiple AWDs are mounted on the cantilever beam are shown by numerical simulation. Optimal arrangement of AWDs based on static deflection amount and vibration control performance found from the numerical simulation is investigated.
