Natural Vibration On A Ship

Natural Vibration On A Ship

Vibrationbehaviour of a model ship in air and in water
Ship Model mountedon springs; vibration excitation and acceleration measurement at any point
Frame withheight-adjustable cross-member for attaching the model
High naturalfrequency of the cross-member owing to enclosed box cross-section with highrigidity and low weight
