Abstract
This paper studies the shear strength of an anti-rust bolt with a spiral oil-guiding slot and oil-bearing hole by conducting a simulation and experiment. A finite element model with the bolt and the clamp tool is developed for simulating the shearing of the bolt in progressive failure analyses. An indirect method is proposed to generate a spiral entity that can produce excellent spiral elements. A clamp tool is designed for the shear experiment of the bolt. Moreover, a substitute calculation method is presented for the shear strength analysis of the special bolt, and the effect of using the oil-guiding slot on shear strengths is considered by reducing the bolt’s radius. The study results show the following: The results of the simulation are in good agreement with the experimental results. One side of the bolt with the oil-bearing hole is first cut off, and the deviation between the result obtained by using the substitute calculation and the experiment’s result is 7.97%.
