A METHOD FOR ACQUIRING REBOUND VALUE, TESTING A RESILIOMETER AND CALIBRATING A SENSOR

摘要

When the resiliometer works, the time T of the timing end point is collected, then the rebound value is acquired according to the direction standard equation or its transformed forms, or the time ti and the corresponding displacement xi during the movement is acquired, then the rebound value is acquired according to the transformed equation of the direction standard equation Whether the resiliometer is qualified can be tested by determining whether the rebound value determined according to the direction standard equation or its transformed forms is equal to the rebound value read by eyes in the range of error, or the hammer of the resiliometer rebounds on an inspection instrument of the resiliometer or on a special steel anvil, whether the resiliometer is qualified can also be tested by detecting whether the rebound value determined according to the direction standard equation or its transformed forms is in the range accepted by the standard of the resiliometer The sensor of the resiliometer is calibrated by establishing a relationship between an original signal output by the sensor and a displacement value acquired according to the direction standard equation or its transformed forms.
