METHODS FOR DYNAMICALLY BALANCING NAVAL MACHINERY IN PLACE
Abstract
The methods and equipment available for balancing machinery in place were reviewed for the purpose of obtaining an i proved and more economical method of maintaining quiet shipboard machinery. T e s udy was limited to the consideration of rotating equipment with rigid rotors. An electrical balancing method, used for shop balancing, was found to be suitable for in-place balancing. Recommended modifications for this equipment include the addition of four electrical networks for plane separation and compensation and the addition of r ferenc ignal generator. None of the available balancing equip ents c isf c orily detect vibrations due to unbalance in the presence of severe background vibr tions which have frequencies within 2 cps of the rotor frequency. The general effect of background vibration is to cause fluctuations in the vibration amplitude and phase angle indicators of balancing equipments. (Author)
