Research of design and vibration reduction of dual mass flywheel with arc helix spring

摘要

In order to reduce torsion vibration of automotive powertrain, angular stiffness formula of arc helix spring was built according to the performance parameter of a C-grade car. Based on the expression, a method of optimization design about arc helix spring is proposed with the variable radian. A new Dual Mass Flywheel (DMF) with 6 arc helix springs is designed. The torsion vibration simulation model of automotive power train is established by Msc. Easy 5 and the system is analyzed. Further, the experiment is made and proves that the design of DMF can satisfy the use of the car.
