CONTACT INTERACTION OF A TORSION SHAFT WITH A SPLINED BUSH IN ELASTICALLY PLASTIC DEFORMATIONS

Torsion shafts are the main elastic element of suspension systems a large number vehicles. To simulate their reaction to action torque, stress-strain state is analyzed taking into account contact interaction with spline sleeve. The features distribution pressure between these bodies established. nature stress concentration in splined hollows shaft head determined. Models and research methods have been developed that make it possible develop recommendations for design decisions vehicle systems. factors determined ensure strength torsion at values its diameters close stem. In case under consideration, this factor firstly head. particular, was found during manufacturing operations there significant plastic deformations loads heads shafts. This decisive substantiating parameters Keywords: shaft; interaction; state; elastically deformation; system
