- Abstract
Based on the design principle of bolt pre-tightening force, the feasibility of reusing high-strength bolts is analyzed theoretically. Analysis suggests that in response to the issue of increased friction coefficient and discreteness caused by repeated use of bolts, some corrective measures such as adjusting rated pre-tightening torque of bolts and increasing thread lubrication can be taken to reduce the adverse effects caused by repeated use of bolts, and it is proposed that whether the pre-tightening force of bolts is within the design range can be used as the determination basis for repeated use of bolts.
