Opis:: The work presents selected results of experimental research on special purpose vehicles used on military training grounds, and bench tests of their main structural elements. The results are connected mainly with identifying the main vibration parameters of those vehicles (regarding weight, resilience and damping), and with the assessment of the level of dynamic loads. The more output data experimental research provides, the more input data we have for designing models. Determined in laboratory tests, weight parameters (regarding weight and moments of inertia), coefficients of stiffness and damping, as well as selected resilience and damping characteristics, are applied in the process of creating the numerical models of assemblies, systems, and complete vehicles. The numerical models created are subject to full verification in order to minimize the differences between the real objects and their representations. The models are applied in multivariate simulation tests of the existing design solutions, upgrading them, or creating new designs. Due to a certain sensitivity of the range of special purpose vehicles, the results of experimental tests and simulation analyses presented in the work are mainly qualitative rather than quantitative.

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:: This paper presents the results of the studies on a special vehicle Polaris Ranger 6×6 800 equipped with the ”Crossbow” antiaircraft rocket launcher, manufactured by TELESYSTEM-MESKO Sp z o. o. Implementation and Manufacture Centre. The supporting structure of the launcher made the main object of the analysis. The essential goal of that undertaking was to obtain a structure of resistance assuring reliable system operation in various conditions of use. In order to reach that goal, the experimental as well as the model tests have been performed on the launcher vehicle. The experimental tests were carried out during multi-variant rides on the paved roads and in the wilderness of significant level of unevenness. Significant information on the level, directions and nature of affecting dynamic loads and the effects of their influence on the vehicle elements. The analysis of obtained results also provided the data required for a development of a model of the object of the studies. A MES model of the object of the studies was prepared in the LS-DYNA system. A high pressure was put on modelling a complex chassis of the launcher and mutual reaction of assemblies and parts. A generalized issue on the own properties was solved – frequencies and associated forms of vibrations of own main assemblies were designated. Resistance calculations were carried out for assumed loads. In principle, loads imposed by normative requirements for a particular class of armament and military equipment were assumed. Loads resulting from potential conditions of use and installation on other carriers were also included. The tests were performed for various load variants. Sensitive elements of the chassis were modified and highly satisfying results were obtained. It gives a reason to think that the chassis is resistant to expected and difficult operation conditions and assures that the whole system will work reliably.
