Opis:: 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.

Opis:: The results of the experimental research on the influence of the special vehicle movement conditions on the body shell and the vehicle crew dynamic load will be presented in the paper. ROSOMAK Wheeled Armoured Personnel Carrier (Wheeled APC), the basic version, was the subject of the research. The research work was aimed at analysis of the dynamic loads resulting from the deterministic inputs and driving on the selected types of surfaces generating random kinematic inputs. The personnel carrier service conditions, measuring apparatus, and testing methods will be described. The vertical accelerations of the selected points of the vehicle, and deflection of the prime and second suspension of the vehicle left side were measured. The time and the acceleration RMS value spectrum charts for the selected implementations will be presented. The cumulative statistics will be shown in the form of a table. The conclusions regarding the influence of the road surface on the personnel carrier driver's working comfort will be formulated. The assessment of the suspension quality will be included in the conclusions. Driving on the smooth surface is comfortable. However, the road surface worsening causes decreased proficiency sense until the exposure limit boundary is reached when the vehicle drives on a poor quality cobble road with 50 km/h speed. The vehicle basic version is not fitted with the seats for assault troops, therefore the influence of the road irregularities on the centre of mass of the body shell, and the driver's and commander's seats were determined. It is recommended to make further tests on the personnel carrier combat and special versions.

Opis:: Since the beginning of the 90’s, a scientific team in the Motor Vehicle and Transport Institute of the Mechanical Department in the Military University of Technology, has been involved in the model and experimental tests of the existing structures of the military vehicles (tanks, combat infantry vehicles and wheeled armoured carriers) in the aspect of their modernization. A part of works is related to the military vehicles included in the army’s equipment and the other parts are related to newly designed vehicles. In both cases issues related to the behaviour of selected assemblies and the whole vehicle, structure during threats posed by the reality of contemporary battlefield or armed symmetric or asymmetric conflicts are analysed. Selected effects of the tests and analyses will be presented mostly within the qualitative scope due to the data sensitivity. Contemporary design of military vehicles requires involvement of various research methods and specialized calculation software. The results obtained during performed various experimental tests make a valuable basis for verification of numerical models used in design process and multi-option simulation calculations.
