Rebound Analysis for the Diesel Engine Pre-Tightened Bolt Using ABAQUS

Abstract:

When the nuts are tightened on the big bore diesel engine through the hydraulic tensioner, the preloaded forces imposed on the studs are often less than the design values. In order to get the difference, finite element method was introduced and stress analysis was implemented in Abaqus. Meanwhile the finite element model was modified based on the real test result. Eventually reliable difference results were obtained and the modified model could be applied in the other research.
