Abstract
To evaluate the adverse effects on diesel under overload operation,taking the power plant of a certain type of diesel engine as the original model,the crankshaft fatigue life under 75%,100%,110%,120% loads is calculated using dynamic stress analysis and fatigue life calculation of 3D finite element when the cylinder cut-in angle is 420°.The boundary conditions of diesel engine such as ignition sequence,gas force on piston,speed,output torque and so on are set for the calculation.The results show that the fatigue life area of crankshaft throw expands obviously with the increase of diesel engine load when the cylinder cut-in angle is 420°.
