Two methods of inertia simulation, energy compensation method and torque control method, using work of electromotor during brake application are discussed in comparison in this paper. Mathematical models are described. Experiment under various brake conditions unfolds the rule of some key factors of energy compensation including working period of electromotor, start point and ending condition of compensation. Comparison experiment shows advantages of the energy compensation method over its counterpart. Limitations as well as corresponding solutions are discussed in the end.

Frequency Variations

A lumped parameter model to predict the high frequency pressure oscillations observed in a water brake dynamometer is presented. It explains how the measured low frequency variations of the torque are a consequence of the variation in amplitude of the high frequency flow oscillations. Based on this model, geometrical modifications were defined, aiming to suppress the oscillations while maintaining mechanical integrity of the device. An experimental verification demonstrated the validity of the model and showed a very stable operation of the modified dynamometer even at very low torque.
