Experimental study on high strength bolt pre-tightening force of friction energy dissipation device

摘要

The pre-tightening force experiment to high-strength bolts of friction-energy-dissipation device were implemented by the turn-nut method and then obtained the linear scale between pre-tightening force and angle of rotation by analyzing the data. This provides a reference for the measurement of bolt pre-tightening force. At the same time computed the stiffness of connection attachments and connected members by Workbench and the pre-tightening force of bolts with related parameters. The comparative results with the experimental data can make a reference for applications of high-strength bolts connection in friction-energy-dissipation devices.
