RESEARCH OF THE DISTRIBUTIONS OF CONTACT PRESSURE AND THE STRESS-DEFORMED STATE OF THE ELEMENTS OF THE STRUCTURES OF THE TORSION SHAFTS OF THE SUSPENSION OF ARMORED VEHICLES

The work demonstrates the need in accounting for the factor of the mutual influence of contact interaction and plastic deformation in the area of the head of the torsion shaft on the strength of the torsion shafts of the suspension of armored combat vehicles in order to achieve improvements in the technical solutions for the elements of the suspension systems of light-armored vehicles, and, accordingly, the tactical and technical characteristics of mobility. An analysis of the effect of varying the properties of materials and the shape of the contacting surfaces on the contact interaction and the stress-strain state of torsion shafts was carried out. In the presence of limitations on the dimensions of the head of the torsion shaft of the suspension systems of lightly armored vehicles, one of the important solutions is the modification of the working surfaces of the spline connection, which makes it possible to reduce the level of contact pressure in the spline coupling on the head of the torsion shaft.
