Analysis of the Screw Thread Connection Strength Based on Nonlinear Finite Element Method

Abstract:

Some parts of the projectile is in screw connection, the stress and deformation caused by screw threads are important indexes of the security, and therefore stress distribution of the connection of thread must be accurately calculated. According to the structural characteristics of threaded connection, nonlinear finite element contact analysis was used, strength of the thread connection part was simulated and analyzed by applying effective loads, and this algorithm was validated.
