Connection forces acting at the joints of a kinematic mechanism are derived from the generalized variables of the mechanism equation of motion using an equivalent-force analysis. The connection force calculation is numerically efficient and is independent of the formulation and solution of the equations of motion. A numerical example illustrates an application to a planar four-bar linkage.
