Experimental Methods and Devices for the Identification of the Properties of Pneumatic Dual Mass Flywheel

Abstract

The torsional vibrations generated by combustion engines installed in vehicles have an undesirable effect on the life and reliability of individual components. Vibration and excited noise reduce the comfort of the operator and crew. The subject of torsional vibration reduction is therefore highly current. One of the options for reducing torsional vibrations is the current use of dual mass flywheels that are included between the combustion engine and the vehicle’s gearbox. An alternative solution to the reduction of torsional vibration is the use of a pneumatic dual mass flywheel. The pneumatic dual mass flywheel is characterized by the fact that it is possible to change its properties during the drive operation. For the purpose of investigating the use of dual mass flywheel in combustion engines, it was necessary to create experimental devices and methodology to identify their properties. The experimental device is possible to identify the operational, strength and expansion properties of pneumatic dual mass flywheels.
