Dynamic Simulation of Dual Mass Flywheel

摘要: New powertrain design poses new challenges in terms of driveline vibration or ultimately in terms of NVH (Noise Vibration Harshness). Current state of the technology for vibration damping in car powertrains is the so-called Dual Mass Flywheel (DMF). The paper deals with creation of MBD model of double mass flywheel based on CAD model of dual mass flywheel produced by ZF. Parameters of virtual model are tuned and compared with experimental measures of dual mass flywheel. Second part of paper deals with dynamic simulation of DMF. Model used for dynamic simulation consists of two bodies and torsion spring with stiffness computed from simulation of full DMF model.
