Bolt is one of the commonly used couplings in various equipment design. It has the advantages of simple structure, convenient disassembly and assembly, easy adjustment, etc. It is widely used in aerospace, automobile and various engineering structures.
The analytical method of traditional mechanics checks the strength of bolts, mainly by applying the principle of force decomposition and translation, solving the mechanical equilibrium equation, and idealizing and formulating by means of theoretical and empirical formulas. The integrity of the connecting member, the path of force transmission, and local refinement of the component (such as stress concentration, stress distribution) are not considered.
Through the finite element method, the overall modeling and local refinement can make up for the defects of traditional mechanical analysis. The application of finite element in bolt strength check is more and more extensive.
