Abstract :
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.
