A New Method of Inertia Simulation in Brake Dynamometer Testing 2008-01-2578
A new method of inertia simulation (named the energy compensation method) using work of electromotor for energy compensation during brake application is presented in this paper, where advantages and disadvantages of three common inertia simulating methods are compared at first. Mathematical model is described. Consequent orthogonal experiment unfolds the rule of some key factors of energy compensation including working period of electromotor, start point and ending condition of compensation. Limitations as well as corresponding solutions are discussed in the end. Energy compensation method is shown to be an effective way of simulating target inertia in brake dynamometer testing.
