摘要

A multi-body system with one degree-of-freedom and friction-affected constraints is considered. The differential equation of motion established by Lagrange's equation of the second kind, the equations of the reaction forces resulting from conditions of kinetic equilibrium, and the friction laws constitute a non-linear algebraic system for the computation of the accelerations. These equations allow the determination of limit values of friction parameters, which assure finite solutions for accelerations. With friction parameters larger than these limit values solutions do not exist or are not unique. The solutions are determined by the direct iteration method. [References: 12]
