Abstract
The structure of DMF-CS with centrifugal pendulum-type absorber was analyzed, and the kinematics differential equation of DMF-CS was set up by using Lagrange principle. The natural frequency of pendulum was deduced and found proportional with the rotate speed of the second flywheel. With this characteristic, the torsional vibration from engine fire frequency can be absolutely eliminated theoretically by appropriately adjusting the structural parameters of the centrifugal pendulum. Further more, the isolation of the pendulum with the other lower frequencies vibration of engine was studied and the rule of vibration isolation was summarized. At last, virtual prototype technology was used to build the model of a domestic car drive-train torsional vibration and simulate the isolation performance of the absorber. It is found the simulation result is in accordance with the theoretical analysis.
