碩士 / 國立高雄科技大學 / 模具工程系 / 107 / The propulsion shaft systems are utilized on most of the ships' propulsion for patrolling, escorting, anti-subs, mine laying purposes. Taiwan Navy's self-constructing ship projects proposed littoral combat ship designs with abilities of stealth, high maneuvering, and seakeeping. The propulsion shaft is non-hollow one -piece forming nickel based alloy design. However, in actual industrial practice, the shaft might be damaged by impacts, vibrations, metallic fatigue, that produce seams or cracks on the shaft. This study concentrates on establishing shrinkage model and utilize both experimental and numerical methods to analyze material dyamics. The numerical model is established by utilizing ANSYS Workbench 18.0 finite element based software to observe shrinkage model crack generation length, degree of damage and available life cycles. The results can enlarge the Naval shaft mechanics data base for further references on ship’s industrial practices.
