Investigation into Bicycle Front Fork Forming Process of Simulation and Experiment

Abstract

This study uses the three dimensional finite element code to examine the plastic deformation behavior of bicycle front fork forging. First the paper used Solid works 2010 3D graphics software to design the bicycle front fork die, and that used rigid-plastic model finite element analytical methods, and assuming mode to be rigid body. The front fork material is titanium alloy Ti-6Al-4V. A series of simulation analyses in which the variables depend on die temperature, billet temperature, forging speed, friction factors, die angle are reveal to effective stress, effective strain, die radial load distribution and damage value for bicycle front fork forming. The simulation combined Taguchi method to analysis optimization. The results of the analysis can be used to stabilize finite element software to forming front fork, and also confirm the suitability of bicycle front fork through experiment optimization.
