Abstract
This paper deals with an identification method for engine rigid body inertia properties based on available accelerometer data at mount locations. Unlike other rigid body direct physical parameter identification methods, here inertia properties are extracted from an assembled engine under operating conditions. In addition to acceleration responses, only mount dynamic stiffness measurements are required and there is no need to measure unbalance forces and moments of engine. Using a linear frequency-domain model of engine, mounts, and chassis, a general algorithm is developed.
