Измерение деформаций при моделировании радиально-ротационного профилирования ободьев колес методом тензометрирования

Abstract

Dimension of strain and calculation on them of the stress field in the metal forming strain measurement method is a well-established way to gather information on the stress-strain state. However, studies of the process of radial rotation profile rims this method has not received proper distribution due to the movement of the deformation zone and the lack of available areas of the workpiece. In this paper, the results of strain measurement in the simulation of this process. Deformation is measured in the elastic zone in the static mode, which gives the opportunity to judge their size and orientation directly in the hearth of plastic deformation. Comparative data experimental and theoretical studies. The coincid ence of the results is a proposal of 10%. It is shown that the magnitude of the meridional stretching deformation depends on the shape of workpiece and number of transition profiling.
