摘要
The study on torsional vibration of diesel engine crankshaft system was carried out. The sum of relative vibration amplitude vector of the V-type six cylinder diesel engine was derived to determine the main and strong harmonic orders. The crankshaft system dynamics co-simulation model of a V6 diesel engine was built using GT-SUITE software and validated by experimental data. Two engine varying displacement schemes, fuel-off and valve-off were simulated respectively. The results indicate that the torsional vibration angle displacement amplitude is greatly increased after cylinder deactivation, of two schemes the amplitude of valve-off is greater than that of fuel-off.
