Similarly, in the frequency sweep test, the resonance point may be included in the test conditions. In that case, change the test conditions and jig con guration, etc., and use under conditions where
resonance does not occur. In addition to the resonance frequency, the inertial force due to vibration may be superimposed on the load cell detection value. (Case where resonance is likely to be a problem)
· When the upper and lower jigs are not restrained. (Ball seat pressure plate, etc.)
· When the mass of the jig under the cell is large and the distance to the load point is long. (Tests with in-tank rods, etc.)
· When a lateral force / moment (lateral displacement) is generated when the specimen is loaded.
