Laser measuring technique for ship propulsion shafting torsional vibration

The principle and method for the torsional vibration measuring of ship propulsion shafting by laser are introduced in this paper.The practiaclly measured data by Laser are compared with those by electrical measuring device and those form theoretical calculation and analyzed.The result shows that the ineasured deta by Laser is satisfactory and reliable.The Laser measuring method is very sim ple. Its device is also easy to mount and does not need any aided ports.It may be effectively applied to various kinds of shafting.espe cially in the case to measure the shafting torsional vibration at an unreachable place.
