G01M 1/00 - Definition
This main group covers:
Methods and apparatus for:
Determining and compensating static or dynamic unbalance of machine or structures.
Determining the moment of inertia of machines or structures.
Static balancing of machines or structures.
Determining position of center of gravity of machines or structures.
Combined machines or devices for both determining and correcting unbalance of machines or structures.
Relationship between large subject matter areas
G01H covers the combination of generation and measurement of mechanical and other vibrations while subclass G01M covers determining unbalance by oscillating or rotating the body to be tested.
G01R covers instruments for measuring electrical variables, which can be used for balancing machines or devices but not specially adapted for this purposes.
H04R covers electromechanical transducers producing acoustic waves or variations of electric variables (current or voltage) while G01M covers determining unbalance by converting vibrations due to unbalance into electric variables.
