Puzyr R. Development of theoretical bases of calculation methods of technological parameters of shaping processes of transport vehicles' wheel rims

Object - the processes of local cold deformation of sheet blanks tool, rotating; subject - the patterns of the radial profiling rotary wheel rims, methods of calculating the stress-strain state, power settings and how to intensify profiling technologies; purpose - improving the technical and economic indicators processes radial profiling rotary wheel rims on the grounds of theoretical principles and methods of forming local calculating energy-power parameters; novelty - first established function according to the parameters of the stress and strain at profiling rims wheels revealed patterns of distribution component of the stress tensor and strain in the peripheral areas of semi-formalized distribution of deformation in the tangential direction dependence of the size and distribution of stresses acting in the meridional direction of spatial form billets, the patterns of distribution of forces and torques on transitions are detected depending on the profiling schemes.
