Themultibody simulation is performed for the same clutch type as the previous calculations, i.e. the technical parameters are compliant. It is an air-actuated push-type friction clutch with 3 discs on the drive side and 2 discs on the machine side. The dynamic simulation model is shown in the Figure 5. With advantage we used available technical parameters and drawings of this clutch, as well as measurement record with several different parameters and variables measured on a real machine. The output of such measurement are time dependencies of air-pressure in the actuating cylinder, friction disc position, ram position, flywheel revolutions, etc. It is helpful to debug the simulation, see Figure 6.

The results of a multibody simulation are plot of kinetic energy in the whole system and its parts, and plot of angular velocities of both drive side and machine side of the clutch. The kinetic energy plot shows the kinetic energy of the whole system as the sum of kinetic energy of both sides of the machine.
