The Research On Simulation And Reliability Of 4V-105 Diesel Engine Crank

This article is in under a exploration 4V-105 diesel engine project topic, through establishes the 4V-105 diesel engine crank link motion gear precise virtual model and the mathematical model in the computer and elastic mesh treatment, then carries on dynamics the kinematics simulation, confirmed the design crank link motion gear not to have the interference, obtained the continuation thoroughly to study this type crank link motion gear in work process movement rule and the stress situation data, according to the result of simulation running on the crankshaft; the results of the crankshaft design strength were studied; through the crankshaft fatigue test, test results show that: Crankshaft rated much lower than the minimum load fatigue, under normal circumstances failure probability to zero, the adequacy of fatigue reserves, researching and developping of the 4V-105 diesel engine crankshaft is reliability.
