Abstract EN
In order to design a reasonable thread connection structure, it is necessary to understand the axial force distribution of threaded connections.
For the application of bolted connection in mechanical design, it is necessary to estimate the stiffness of threaded connections.
A calculation model for the distribution of axial force and stiffness considering the friction factor of the threaded connection is established in this paper.
The method regards the thread as a tapered cantilever beam.
Under the action of the thread axial force, in the consideration of friction, the two cantilever beams interact and the beam will be deformed, these deformations include bending deformation, shear deformation, inclination deformation of cantilever beam root, shear deformation of cantilever beam root, radial expansion deformation and radial shrinkage deformation, etc.; calculate each deformation of the thread, respectively, and sum them, that is, the total deformation of the thread.
In this paper, on the one hand, the threaded connection stiffness was measured by experiments; on the other hand, the finite element models were established to calculate the thread stiffness; the calculation results of the method of this paper, the test results, and the finite element analysis (FEA) results were compared, respectively; the results were found to be in a reasonable range; therefore, the validity of the calculation of the method of this paper is verified.
