Beschreibung
Zusammenfassung:	The invention discloses an engine high-strength bolt load measuring device and method with a temperature compensation function. The engine high-strength bolt load measuring device comprises a to-be-measured high-strength bolt with a drilled hole, a tubular base strain gauge, a temperature sensor, a bonding and curing filling body, a wiring terminal and a top sealing structure. The tubular base strain gauge is of a hollow structure, and the base of the tubular base strain gauge is attached to the bottom of the drill hole. The temperature sensor is arranged above the sensitive grid of the tubular substrate strain gauge; a gap area between the hole wall of the drill hole and the tubular base strain gauge is completely filled with the bonding and curing filling body; the wiring terminal is connected with a lead of the tubular base strain gauge and a lead of the temperature sensor; and the top sealing structure completely covers the wiring terminal and the upper space of the drill hole and is in contact with the h
