✦ Synopsis

The work presented is of a study of torsional vibrations of a driveline under static torque and excited by engine torque fluctuations. It includes the design of an experimental set-up and a computer software to predict dynamic behaviour and seek efficient technical solutions. A finite element model is used to study current systems and perform transient analyses. Basic linear elements are used and non-linearities such as a multi-staged clutch with dry friction and gear backlash are taken into account. The time response is calculated and a pseudo-modal method is used. An experimental set-up of the whole driveline has been designed and built to allow simulation of the basic torsional phenomena occurring on the vehicle driveline under input torque from 0 to 200 Nm, and, moreover, to validate numerical models. Furthermore, prediction and experiments on two new vehicles are in quite good agreement.

The dynamic behaviour of an adiabatic adsorption column is described by a mathematical model which includes the axial dispersion of mass and heat as well as external film and pore diffusional resistances to mass transfer. The resistance to heat transfer is assumed to reside in the external fluid fil
