| Abstract | This research focuses on a study of failure mechanism of long tail shafts which are major machinecomponents in mechanical transmission systems of diesel engines in the cut-stern Kolek boats, the importanttraditional fishing boats for fishermen in Kaoseng community, located on the Coast of Songkhla Lake. From onsitedata collection of the failure of long tail shafts, it appears that the shaft suddenly fractures into two pieces whileoperating. When investigating the failure of shafts by examining on surface cracks, it shows that cracks initiated fromthe fillet shoulder of shafts. By analyzing the failure mechanism, it reveals that the weak point of shafts is at thearea which has a high concentration of stresses. In the experimental program for the data above, different loadingsare applied to long tail shafts to evaluate which load that the mechanisms of failure occurred. The conditions ofloadings are No-load, Full-load, and Over-load. The benefit of this research will be used in designing new andappropriate long tail shafts. |
