DEVELOPMENT OF APPROACHES, METHODS AND MODELS OF RESEARCH OF DURABILITY AND LONGEVITY OF TORSION BILLOWS OF THE SUSPENSION SYSTEM THE LIGHT ARMORED VEHICLE

The analysis of materials on approaches, methods and models research strength durability torsion shafts systems suspension light armored vehicle is carried out. It concluded that despite the existing significant theoretical developments, elastic-plastic deformation highly loaded structures, including shafts, requires development adaptation appropriate models. approach to a number studies this issue also needs be developed. As result researches, following model stress-strain state was performed. generalized parametric description shaft contains varied design technological factors process parameters. mathematical bar incremental type has been formulated. accounts for contact elasto-plastic material bar. At same time, depends loading history. A provides advantages in justifying rational technical solutions. This applies both Also, all at stages life cycle bars are taken into account. These have interplay. Ultimately, determined design, operational parameters satisfy conditions increased bars. mechanical physico-mechanical properties used manufacture another important factor with regard these criteria. Accordingly, complex workflow established order improve vehicles characteristics. Keywords: vehicle; performance characteristics; shaft; systems; state; strength; durability;
