A TWO-MODEL APPROACH FOR THE IMPROVEMENT OF A FIXED TANK VEHICLE'S VERTICAL AND LATERAL DYNAMICS

摘要

The subject of this paper is to optimize the dynamic performance of a fixed tank biaxial vehicle, with respect to its vertical and lateral performance. For the vertical description of the fixed-tank vehicle, a linear full-car model with ten degrees of freedom is utilized, while its lateral description is determined according to international regulations. All the involved design parameters, such as suspension characteristics and tank's supports, are included in the optimization process, so that both the vertical and the lateral acceleration of vehicle's centre of mass are optimized. For the simulation tasks two distinct cases of road profiles are considered, while the optimization procedure is carried out using Complex method.
