Study on Tightening Torque of Card Plate in Aircraft Structural Strength Test

  • In order to determine the short tightening force of the card plate in the aircraft structural strength test,the screw rod is tightened according to the general card plate loading system connection and assembly form,the calculation formula of bolt tightening torque is deduced,and the test results confirm its validity and rationality.Based on the characteristics of the card plate transmission,considering the multiple factors,the selection of the pre-tightening force of the card plate welding cup is given by the force analysis.It can be made a reference for calculating and setting the re-tightening force in the general aircraft structural strength test.
