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.
