Abstract

An engine bench is utilized to perform durability test, performance test and other tests of a vehicle engine. Mechanical system of the engine bench consists of tested engine with clutch, dynamometer for absorbing engine power and coupling shaft to connect the engine and the dynamometer. As the stiffness of the clutch varies widely, it is necessary that the shaft torque control of the engine bench becomes stable for the variation of the stiffness of the clutch. In addition, an inertia compensation control of the coupling shaft is necessary for the engine load torque control. The conventional inertia compensation control method of the coupling shaft needs the pseudo-differential of the angular velocity of the dynamometer. In this paper, a stability analysis of the shaft torque control method that we proposed earlier is implemented. and we propose the inertia compensation control method of the coupling shaft that does not need the pseudo-differential of the angular velocity of the dynamometer.
