    Load cases to analyse a bus-chassis part?

    Hi, I have to evaluate via FEM a chassis part from a bus: the last transverse beam, which supports part of the motor weight. I am just wondering about the load cases I must consider. If the beam is 3-DOF restricted in its end, and the motor is simulated as a point-mass over the beam linked to...

    Hello everyone I am working out the apropiate size of the end transverse beam in a coach/bus which has a 3 to6 Ton trail tied to a hook in that beam. Does anybody know the appropiate horizontal/vertical force magnitude that I should take into account for my calculations? I consider braking (1...
