Comparative analysis of underfloor wheel lathes with monolithic and bolted structure in terms of static and dynamic properties based on the results of FEM analyzes
Department of Machine Technology, Faculty of Mechanical Engineering, Silesian University of Technology, Poland
The subject of the research was Underfloor Wheel Lathes de-signed to regenerate the profiles of the running wheels and brake discs of heavy rail vehicles without removing the wheelsets. These machines can also be used to regenerate wheel sets in trolleys dismantled from vehicles or the wheel sets themselves. The machine tools operate in a pass-through system. Two machine tools differing in the structure of the supporting sys-tem were tested: monolithic and folding. Conclusions are based on the re-sults of the FEA simulation. They concerned the influence of the type of supporting structure and connection between the bodies on the static stiff-ness, forms of vibrations and dynamic stiffness of machine tools.
