Optimum Design for Inserted Tooth Slips Setting Process Based on the Furrow Effect

This work established a finite element analysis (FEA) model of an inserted tooth-type slip assembly under bear setting load and axial load, calculated the differences between teeth sidetracking packer slip-formed furrow shapes on casing face, analyzed reliability tooth packer. The orthogonal optimization structural parameters was carried out basis effect. Finally, experiment conducted with developed to verify correctness FEA simulation results. results show that in calculation process slip, it is not only necessary consider friction coefficient, but also effect ridge coefficient. corresponding coefficient varies according different effects occurring surface caused by various types slips. related sharpness tips sharper tips, more obvious is. Under dual adhesion effect, carbide feed into wall produce uniform distinct indentation premise meeting strength ensure reliable hanging optimal combination obtained taking bite depth uniformity as objective function: installation spacing L = 10 mm, angle α 80°, diameter d wedge β 6°. standard deviation optimized 74.45% lower than before optimization. research this paper basically meet requirements engineering applications.
