Paper presents the results of numerical research on the influence of the movement conditions (velocity and various types and parameters of obstacles) on the level of dynamic loads of the body shell and the vehicle crew of the basic version of Wheeled Armoured Personnel Carrier (Wheeled APC) ROSOMAK. The research work was aimed at analysis of the dynamic loads resulting from the overcoming various terrain obstacles. Kinematic constraints acting on suspension used during tests were random and deterministic, e.g. sine, cosine, triangle as well as mixed, imitating fallen tree trunk on smooth surface. Simulations were carried out with the genuine proprietary software for numerical analysis of dynamics of multi-axis vehicles equipped with independent suspension. The paper consists description of the mathematical model of multi-axis vehicle, deterministic and random generated inputs and range of performed tests. Time courses of displacement, velocity, vertical and angular (longitudinal and transverse) accelerations were determined for chosen parts of vehicle. Paper also contains time courses of deflection for every suspension wheel and dynamical reactions of the ground as well as selected time charts and cumulative statistics. Finally paper presents conclusions formulated about dynamic loads of APC ROSOMAK depending on parameters and types of obstacles and vehicle velocity.
