| Abstract: | A finite element method is presented to determine the steady state elastic responses of planar mechanisms with distributed mass, operating at a prescribed input rotary speed. The nonlinear governing equations of the system are derived from the Lagrange equation. The concentrated masses and rotatory inertia are considered in the formulation. The geometric nonlinear terms of the strains are also included. |
