Method for determining imbalance of rotating object i.e. unvulcanized tire, for aircraft or mold for manufacturing tire for aircraft, involves optically measuring volume of object and determining imbalance of object

摘要

The method involves optically measuring volume of an object i.e. unvulcanized tire (1), by determining an outer contour and/or an inner contour of the object, and determining imbalance of the object. The volume of the object is changed corresponding to the imbalance of the object. A specific volume corresponding to parts of the object is added and/or removed. The unvulcanized tire in a tire model is positioned such that the imbalance of the object is balanced by asymmetry of the tire model and/or pressure bladder in interior of the tire.
