| description | Аs a result of the study, a three-dimensional finite element
model of a wheelset with rail sections is developed using a finite
element of the ten-node tetrahedron type, and the maximum
tangent stresses and maximum equivalent stresses are determined
according to the theory of Mises and Dang Wang. It is shown that
the maximum shear stresses are observed at a point located at a
depth of 4,5–5,3 mm below the surface of the wheel. In case of emergency (short) braking, the maximum stresses take place on
the surface of the wheel. With prolonged braking (the movement
of the train on a long descent), maximum stresses occur at the
point of transition from the disk to the rim on the inside of the
wheel, and the value of these stresses is 2,5 times higher than in
emergency braking mode. The finite element method is used to
determine the stress-strain state of the wheelset of a freight car
during braking. |
