Finite element-based special thread design method, system and device and medium

The invention discloses a special thread design method, system and device based on finite elements and a medium, and the method comprises the steps: building a geometric model based on the physical state and physical parameters of a special thread; optimizing the constructed geometric module based on the installation condition of the special thread; performing finite element simulation calculation on the optimized geometric model based on material performance parameters and boundary conditions of the special thread to obtain stress-strain parameters of the special thread; and based on the stress-strain parameters of the special threaded joint, judging whether the special thread has a yield phenomenon or not, and if not, outputting a design result. According to the invention, cyclic calculation and improvement of the structure are realized, the laboratory trial-production frequency and test cost can be reduced, and the test period is shortened. 本发明公开了一种基于有限元的特殊螺纹设计方法、系统、装置及介质，包括：基于特殊螺纹的物理状态和物理参数，构建几何模型；基于特殊螺纹的
