Method Study to Determine Tighten Torque of Thread Fasteners

Abstract:

To meet the operating requirements and give full play to the efficiency of thread fasteners, a method to calculate tighten torque was developed on the basis of pre-tightening force-torque characteristic curve. Compared the traditional method depended on empirical values, the method proposed in the paper can not only consider the theoretical analysis, but also combine experiment results. Through calculating the tighten torque of a car engines bearing bolts by pre-tightening force-torque characteristic curve method, and comparing the results and the practical torque value, it demonstrates that the pre-tightening force-torque characteristic curve method can develop more efficiency of the bolt.
