Case Study:
Engine Weight Reduction
Client
Commercial Vehicle Engine OEM
Objective
Reduce weight of crankcase without sacrificing its capacity to withstand peak firing pressure
Scope
- Perform thermo-structural analysis on engine assembly using: thermal loads determined from coolant jacket CFD anlaysis; firing loads determined from crankshaft dynamic analysis; and assembly loads including bolt pretension and mechanical interference
- Provide design recommendations for crankcase weight optimisation taking into account manufacturability.
Success
- Crankcase weight reduced by over 8%
- Fatigue safety factors increased in critical areas
