We present a dynamic simulation of a wire rope involving both contact phenomena with a winchdrum and hydraulic dynamics using a finite element method. Rapid winch operation often causes a disorderly winding of wire rope, which is important on quality of wire rope. Dynamic simulation is, therefore, required for a design of hydraulic winch system on construction machinery. The wire rope is modeled using by truss elements considering large displacement motion. The contact between the wire rope and a winch drum ismodeled using by variable-length truss elements and bilinear spring elements. Simulation results show that some lever operation cause the rope looseness and intense pressure fluctuation. Moreover, we propose a slowstop winch system and verify the system performance by the simulation.
