Abstract
PURPOSE: To increase a resonance frequency at the time of measurement by increasing the rigidity of a unit by providing several contactless displacement detectors symmetrically on a center line between an excitation part and force detection part.
CONSTITUTION: By jig 18 combined to force detection part 17 and test-piece fitting table 13 fixed to excitation unit 11, testing spring 19 is mounted so that its center line will agree with that between detection part 17 and unit 11. Each movable piece 23 fixed at one terminal to guard part 13a of table 13 and at the other to guard 18a of jig 18 via a magnetic member for displacement detection is provided without coming in contact with the inner wall of fixed piece 22 provided with a coil at its inner circumference, and several contactless displacement detectors 21... formed of the displacement-detecting magnetic member and fixed piece 22 are arranged in parallel symmetrically on the center line between unit 11 and detection part 17. This constitution allows an increase in rigidity of the measuring unit, vibtates spring 19 at a resonance frequency and realizes excellent tests over a broad frequency band.
