A Study on the Calculation f Maximum Strain of Propeller Shaft Coating Materials

Recently to achieve the anti-corrossive effect in propeller shafts the coating technique with suit-able coating materials is available instead of bronze-sleeved shafts. In this case the coating mate-rials in service must not be delaminated from the shaft and the crack must not be originated. Thus the various performance and security test for coating materials of propeller shaft must be carried out under the real conditions or more severe circumstance. The most important factors effecting on the funtion of coating materials in propeller shaft are the strain and the environment of sea water. In this paper therefore the maximum possible strain which can be occured in real propeller shaft was calculated based on IACA standard classification rule in order to give the proper level of strain to the test samples in performance test of propeller shaft coating materials.
