ARTICLE INFO A systematic, sensitivity based design process to perform durability simulation of a crankcase for a six cylinder four stroke truck diesel engine with a peak firing pressure (PFP) of 180bar is presented. Traditionally, a trial and error method is used when a design fails to meet the strength and the design criteria, which often conflict. This old approach not only is time and cost consuming but also does not provide insight into structural behavior. This proposed process uses

CFD, Multibody and FEA technologies such as design sensitivity analysis, coolant flow analysis, graphical user interface, etc. It handles multi-discipline design criteria simultaneously and provides design engineers insight into structural responses for durability, and stiffness concerns and a means for systematic design review for its strength and quality improvement. Involving Identifying and considering PFP, inertia loads, thermal loads and assembly loads. This needs performing crankshaft dynamic and thermal analysis on multibody software. The obtained loads were then applied to the FE model and boundary conditions were applied according to the engine assembly.
