How to model wheel and bogie as a rigid body?

      Dear community,

      I want to model the wheel and the bogie as a rigid body, in which I have as given the mass of the wheel, the mass and the inertia of pitch motion of the bogie. How can I do it in Ansys Workbench ?

      Thanks in advance

      Please try changing the stiffness behavior under the Geometry Details:

      Thanks for your response, yes I know to define rigid body, but how I have to define the mass for the wheel and the the mass and the inertia of pitch motion of the bogie in Ansys Workbench. Thank you so much

      The mass of the wheel and moment of inertia will be determined by Mechanical. Following is a typical example. Do you want to edit the same?

      Yes, how to modify it ? should I calculate the volume and then the density to put it in the material property
      Thnaks a lot

      The volume is determined by Mechanical based on your geometry. You can modify the density in Engineering Data.
