DYNAMIC RESPONSE ANALYSIS OF A STRUCTURE WITH ADJUSTABLE NON-PROPORTIONAL DAMPING AND APPLICATIONS TO RIDE COMFORT OPTIMIZATION

Abstract

Abstract: A method for the analysis of the dynamic response of structures with adjustadle non-proportional damping is presented. The power spectrum and time history can be obtained from the transfer function and impulse response function computed from the non-proportional damping matrix. In addition, a method is also presented to estimate the reliability index of structures due to multiple random excitations by use of the transfer function, and to assess the sensitivity of the reliability index to variations of damping parameters. This method was successfully applied to the ride comfort optimization of a truck running on an unven road.

Key words: Damping, Impulse, Reliability, Truck
