Selected possibilities of using multibody models for the optimization of mechanical vehicle structures

The purpose of this article is to demonstrate the possibilities of applying numerical analyses by combining two systems for modeling the dynamic properties of multibody systems and the finite element method.By optimizing the vehicle suspension for a given road profile, the possibility of increasing passenger ride comfort is shown. In the example, the optimization task involved minimizing vertical body accelerations while the vehicle is driven on a given surface at a specified speed. As a continuation of the work undertaken, experimental verification of the obtained results through tests on real vehicles is planned.
SELECTED POSSIBILITIES OF USING MULTIBODY MODELS TO OPTIMIZE THE DESIGN OF MECHANICAL VEHICLES
The aim of this paper is to show the applicability of virtual simulation, using a combination of two dynamic systems modeling – multibody and finite element method. By optimizing the vehicle’s suspension for a given road profile there will be shown the possibility of the increase of traveling comfort of passengers.
Optimization task is conducted to minimize the vertical acceleration in the body while driving the vehicle on a given surface at a fixed speed. It is planned to extend the scope of the work and verify obtained results with experimental tests performed for real-live vehicles. (…)
