Equations of motion of vibration machines with a translational motion
Generalized models have been built of one-, two-, and three-mass vibration machines with a rectilinear translational motion of platforms and a vibration exciter in the form of a ball, a roller, or a pendulum auto-balancer. In the generalized model of a single-mass vibration machine, the platform relies on an elastic-viscous support with the guides enabling the platform's rectilinear ...

13.4: The Lagrangian Equations of Motion
Conservative Forces. If the various forces in a particular problem are conservative (gravity, springs and stretched strings, including valence bonds in a molecule) then the generalized force can be obtained by the negative of the gradient of a potential energy function – i.e. ( P_{j}=-dfrac{partial V}{partial q_{j}}).In that case, Lagrange's equation takes the form
