Example for mechanical blockset MECHMACS

Engine with a winch

An electric motor DCE with an attached rotating shaft drives a set of gears. A drum, connected to the output gear, winds up a rope which carries a weight. DCE block (direct current engine) is models the electric motor SMD block (spring mass with damper) is models the long rotating shaft RGB block (rigid gear box) is models the gears and the drum and also performs the transition from rotation to translation

To set up a simulation, the user wires blocks in the sequence of their occurence in the mechanical system into a Simulink block diagram and enters parameters into block-specific dialog boxes. These parameters determine the dynamic block behavior under implied displacements, velocities and external forces.

Using MECHMACS-C for this example results in a speed up of 10 or more (without animation).
