Experimental Determination of a Powertrain's Inertia Ellipsoid

Pavel Brabec, Robert Voženílek, Miroslav Malý


This paper summarizes current scientific knowledge and the results of a study focused on the determination of a powertrain's inertia ellipsoid. The work deals with the application of methods for the experimental determination of the inertia matrix and summarizes their basic potential. The work describes a proposed computational algorithm by means of which the inertia ellipsoid can be determined. The experimental section of the work presents the results of measurements for internal combustion engines (powertrains).
