COMPUTER MODELING OF THE STRENGTH OF A PRESSED JOINT OF A SOLID-ROLLED WHEEL WITH THE AXLE OF A WAGON WHEELSET, TAKING INTO ACCOUNT DEVIATIONS IN THE MACROGEOMETRY OF THE MATING SURFACES AND THE SPEED OF THE CARRIAGE

The article presents the results of the development of computer models based on the finite element method for assessing the strength of a pressed joint of a wheelset with a solid-rolled wheel. A set of calculations was performed, the results of which were used to obtain the dependences of stress changes and contact pressure on the speed of the car at different values of interference and deviations of the macrogeometry of the mating surfaces
