Title:
METHOD, USE, AND DEVICE FOR ULTRASONIC DOUBLE-WAVE MEASUREMENT OF PRE-TIGHTENING FORCE AND TEMPERATURE OF SOLID MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/005061
Kind Code:
A1
Abstract:
A method for the ultrasonic double-wave measurement of a pre-tightening force and temperature of a solid material, comprising: (S01) obtaining a first modal wave sound time (TS0) and a second modal wave sound time (TL0) of an ultrasonic double-wave of a solid material at a first temperature and stress state; (S02) measuring a first modal wave time (TS) and a second modal wave time (TL) of the ultrasonic double-wave of the solid material in an unknown state; (S03) obtaining a first modal wave temperature influence coefficient (KTS) and a second modal wave temperature influence coefficient (KTL) of the solid material, and a first modal wave pre-tightening force influence coefficient (KFS) and a second modal wave pre-tightening force influence coefficient (KFL) in a solid material to be measured having the same specification and geometric shape; and (S04) obtaining a relative change relationship of ultrasonic double-wave sound times according to first-order or second-order Taylor approximation, and jointly solving to obtain a measured pre-tightening force (F) and a measured temperature (T). A pre-tightening force and an average temperature can be obtained simultaneously by means of currently measured ultrasonic double-wave sound times and some constants, the calculation method is simple, the efficiency is high, a variety of measurement errors can be avoided, and the method has a wide range of applications.
