Dynamics of rigid bodies example, this procedure will show its limitations if applied manually, when the number of bodies becomes large. Finally, we shall present a variational approach based on the virtual power principle and use this second approach to treat the same example.AMPLE 发表于 2025-3-27 12:56:18

Dynamics of rigid bodieseedom will be introduced and illustrated via simple examples. Then, we shall develop the Newton-Euler procedure which produces the equations of motion relating the motion of the bodies (i.e. the evolution of the generalized coordinates) to the forces/torques applied to the system.

Road vehicles: wheel/ground modeloperties (stability, riding comfort, etc.). From the mechanical point of view, a vehicle is intrinsically of a multibody nature. Depending on the application, the model refinement can vary noticeably, while being rigorous with respect to the envisaged analysis. For instance, one could wish to check的阐明 发表于 2025-3-28 10:45:23
