| Development of lumped-parameter mathematical models for a vehicle localized impact
Witold Pawlus, Hamid Reza Karimi* and Kjell Gunnar Robbersmyr
The Journal of Mechanical Science and Technology, vol. 25, no. 7, pp.1737-1747, 2011
Abstract : In this paper, we propose a method of modeling for vehicle crash systems based on viscous and elastic properties of the materials. This
paper covers an influence of different arrangement of spring and damper on the models’ response. Differences in simulating vehicle-torigid
barrier collision and vehicle-to-pole collision are explained. Comparison of the models obtained from wideband (unfiltered) acceleration
and filtered acceleration is done. At the end we propose a model which is suitable for localized collisions simulation.
