METHOD AND APPARATUS FOR DETERMINING MOMENTS ACTING UPON AN OBJECT UNDER MEASUREMENT

摘要

: A method and an apparatus for determining at least one moment acting about a predetermined axis of an object placed on a force measuring apparatus in a flowing medium. In order to compensate measurement errors caused by a displacement of the center of gravity of the object upon application of the flowing medium exactly defined variable forces are applied to the object prior to the application of the flowing medium. The displacement of the center of gravity of the object is determined in dependence on the force variation and then taken into consideration when evaluating the force and moment measurements.
