Description
Summary:Military vehicles, destined either for transportation of goods and personnel, or for battle missions, move in most situations on unpaved roads. Average movement speed is limited by suspension performances, which have to ensure a constant contact between vehicle's wheels and rolling track. Other factors with influence on minimum movement speed on heavy terrains (imposed by specific standards: STANAG - Standardization NATO Agreement) are represented by driver's physical resistance and behaviour of goods when submitted to shocks and vibrations. For the driver's comfort there can be used independent suspensions for chairs, but in case of transported goods is more difficult, especially when the cargo is fragile and expensive (communication equipment, radars, IT etc.). Therefore, it is very important to study means to reduce vibrations and shocks, using vibration damping materials. Experimental research conducted within present study aimed to analyse vibration isolation elements made of rubber, which have been mounted inside transport boxes. This solution is important to be interoperable and ensure a simplified version of logistics, with the use of containers or standardized transport boxes. Experimental tests aimed to determine material properties, which have not been provided by the manufacturer, and the results have subsequently been used for modelling-simulation of vibration isolation elements behaviour. Virtual model was validated by experimental research consisting in applying composed axial stresses to the analysed materials.
