Experimental Study on Torsional Vibration of Dual Mass Flywheel

To verify the damping effect of dual mass flywheel, the experiment is designed in use of power-transmission test-bed and rev-torque testing apparatus, and dual mass flywheel of DCT transmission system DQ250 is used to test its damping effect in the experiment. Kinds of conditions of car, like idle condition, run condition, climb condition, are simulated in experiment. The results show that different engine revs and loads, different damping effects of dual mass flywheel. The high engine rev and the more load, the better damping effect of dual mass flywheel.
