Consideration on Regard to Fatigue Safety Life in Operating Condition of Diesel Engine Cylinder Head

Finite element analysis of fatigue damage in passenger-car diesel engine cylinder head under cyclic thermo-mechanical loadings

In this article, the thermo-mechanical fatigue lifetime of the cylinder head of a passenger-car diesel engine has been estimated. At the first stage, stress and strain distributions in the cylinder head have been calculated using the two-layer visco-plastic model, available in the ABAQUS software. The calibration of the model was performed, using correlating of simulated hysteresis curves and l...

Evaluation of quenching process on low cycle fatigue life for cylinder head

Due to the complex geometry and thermos-mechanical loading, cylinder heads are the most challenging parts among all parts engines. They must endure cyclic thermal and mechanical loading throughout their lifetime. Cast aluminum alloys are normally quenched after solution treatment process to improve aging responses. Rapid quenching can lead to high residual stress. Residual stress is one of the ...

Fatigue Analysis and Optimization of Crankshaft of V8 Diesel Engine

The crankshaft is one of the most critically loaded components as it experiences cyclic loads in the form of bending and torsion during its service life. Its failure will cause serious damage to the engine so it’s important at the time of design to verify fatigue strength. More challenges in crankshaft design due to increasing vehicle payloads, lower weight requirement, higher efficiency and lo...
