Bond graph modelling and simulation of a variable inertia flywheel

In this paper, a two terminal hydraulic cylinder-motor system attached to a variable inertia flywheel is modelled and simulated to investigate its dynamic performance. In contrast to the constant inertial flywheel, the variable inertia flywheel takes care of the jerk of the dynamic system at the time of fast speed change or sudden speed reversal by suitably adapting its moment of inertia. Bond graph simulation technique is used to model the system as it is a unified strategy suitable for multi-domain modelling
