GEMİ TEKNE TİTREŞİMİ

Vibration has always been an important subject of great interest to shipbuilders and marine engineers, because of its adverse effects both on the ship’s structure and on the comfort of the crew. With the increase in complexity of vibration, the problem of avoiding vibration seems to be getting more rather than less difficult. Vibration is also a problem which is more amenable to mathematical analysis than are many of those connected with ships. Since many possible sources of vibration may exist on board, we are still far from the complete solution of all problems in ship hull vibration. In warships, the addition of sensitive equipment such as radar and sonar has given a request for reducing the vibration to an absolute minimum in order to allow such devices to operate effectively. With the increasing importance of vibration in warships for reasons of defense and offence, more time is being devoted to the subject by the navies of the world. The dangers from acoustic and pressure operated offensive weapons have also focused attention on hull vibration in general and on the noise emitted by hulls, appendages and propellers, which in many cases is associated with some form of hull vibration. As a result, the hull girder vibration is an important problem in all maritime countries.
