The torsional vibration of a marine

The torsional vibration of a marine propulsion shafting
system may cause shafting failures and should thus be carefully considered at the design stage. The regulations of many
shipping registers [2-5] require that torsional vibration of the
shafting system should be calculated at the design stage, and
then measured during sea trials. There are many instruments available to measure torsional vibration, such as the Geiger
torsiograph, the electrical torsiograph, the laser torsiograph
and electrical strain-gauging equipment. Electrical torsiographs are widely used nowadays, and the vibration pick-up of
this system is usually located at the free-end of the shafting
system

register pengiriman [2-5] mengharuskan getaran torsional dari
sistem shafting harus dihitung pada tahap desain, dan
kemudian diukur selama percobaan laut. Ada banyak instrumen yang tersedia untuk mengukur getaran torsional, seperti Geiger
torsiograph, yang torsiograph listrik, torsiograph Laser
dan peralatan regangan-mengukur listrik. Torsiographs listrik banyak digunakan saat ini, dan getaran pick-up dari
sistem ini biasanya terletak di bebas akhir shafting
