The extortions that result in the vibrations of a hull of the combat vehicle have an impact on the tracked combat vehicle during the off-road driving. They may have a negative impact on the crew, internal equipment, shooting accuracy. A level of the hull loads depends on quality of the suspension system, which main responsibility consists in minimising an amplitude of the vibrations. Therefore, it is necessary both to improve a structure of the suspension system, and its components, as well as their optimisation. The tests of the driving smoothness of the vehicle and quality of the suspension elements can be realised both within a frame of the model tests and while driving in the real conditions. The assessment criteria of the driving smoothness are directly related to the negative influence of the vibrations to the human body. The suspension quality should be assumed both upon an execution of the vehicle prototype, and during the design or modernisation phase. It results both in reducing the time, and minimisation of the costs and risk related to the structure development. The model tests enable to evaluate the driving smoothness and comfort prior to an execution of the prototype. The tests on the test tracks in the final phase of the development are carried out in order to evaluate the driving smoothness.

The work describes the experimental test methodology and results obtained during the experimental crash tests involving passenger cars and the prototype concrete protective barrier, which was built according to the original design prepared by the authors of this article. The crash tests involving a vehicle and the protective barrier cover the experiment results in three basic areas: severity ofthe collision impact on vehicle passengers, the impact on a vehicle and deformation of the road protective system. Applied testing procedures meet the requirements of the national standards, that make the equivalents of the European standards EN-1317-1:1998, EN-1317-2:1998, EN-J 317-3:2000. The tests have been performed for selected crash criteria (TB11 and TB32), for a normal restrain level (N2), using three passenger's cars (Dodge Neon and 2 units of Suzuki Swift). Applied testing procedures meet the requirements of the national standards [1-5]. The work presents examples of experimental test results in three basie areas: intensity of the crash impact on the vehicle passengers, the impact on a vehicle and deformation of the road protective system. The test results have been presented in a form of courses of speeds and accelerations along the vehicle body axes x, y, z. Acceleration severity index (ASI), theoretical head impact velocity (THIV), post-impact head delay (PHD), vehicle cabin deformation index (VCDI) and deformation levels of the road protective system (W) have been also defined.

The work describes model and experimental tests on the road restraint systems with particular attention to vehicle collisions with a concrete protective barrier. Vehicle and protective barrier crash tests include the experiment results in three basic fields: intensity of influence of the collision effects on vehicle passengers, collision impact on a vehicle and the road restraint system. It presents a test track concept as well as criteria for performing and evaluating the crash tests with a passenger vehicle and a safety barrier. The experimental tests were performed according to the test methodology recommended by the standard [2]. Examples of model test results were compared with experimental test results obtained on the test track.

W pracy opisano badania modelowe i eksperymentalne drogowych systemów zabezpieczających ze szczególnym uwzględnieniem zderzeń pojazdu, ze sztywną barierą zabezpieczającą. Badania zderzeniowe pojazdu z barierą ochronną obejmują wyniki eksperymentu w trzech podstawowych obszarach: intensywność oddziaływania skutków zderzenia na osoby znajdujące się w pojeśdzie, skutki oddziaływania zderzenia na pojazd oraz odkształcenie drogowego sytemu zabezpieczającego. Przedstawiono koncepcję toru badawczego oraz kryteria przeprowadzenia i oceny próby zderzeniowej samochodu osobowego z betonową barierą zabezpieczającą. Badania eksperymentalne zrealizowano zgodnie z metodyką badań zalecaną przez normę [2]. Przykładowe wyniki badań modelowych porównano z wynikami badań eksperymentalnymi uzyskanymi na poligonowym torze badawczym.
