Loss of kinetic energy is equal to:

Energy loss solved by this method is ideal. In reality the energy loss will be higher due to clutch slippage caused by slow clutch engagement. The difference of the system energy before and after clutch engagement is energy loss. The kinetic energy dissipates into thermal energy. To understand the relation between ratio of moments of inertia, transmitted energy and energy lost, see Figure 4.

2.3 Simulation approach Multibody simulation is a method of numerical simulation consisting of rigid or elastic bodies connected by various kinematic constraints or force elements. Unilateral constraints, such as contacts, may be accompanied by Coulomb friction models etc. Ultimately it is a very powerful tool to investigate, optimize, and verify machine mechanisms. To investigate the friction clutch engagement we used MSC Adams/View software.
