Assessment of ship shafting alignment quality taking into account the stress state of the material
Abstract
The article touches upon the fact that poorly executed alignment of the ship's shafting during the construction or repair of the vessel often leads to its destruction, which is fatigue-like. In some cases, ensuring the alignment of all shafts and bearings also does not guarantee against premature destruction of the elements of the shafting. The main factor determining the durability of the shafting is the stress state of its material. The versatility of the loads acting on the shafting and the complexity of their determination do not allow us to obtain the stress state of the material by calculation with the necessary accuracy. It has been proposed to use the capabilities of a modern instrument base to monitor the stress state of the shafting, an example of such use has been given.
