Research of Simulation Technology in Low-stress Machining on Tooth Surface of Spiral Bevel Gears Used in Aviation Industry

摘要

This paper had 3-dimensional models of a spiral bevel gear and a cutter in real size assembled in accordance with the milling process and transformed them into the finite element analysis (FEA) code. Then several researches on simulation methods of this milling system had been conducted, and stress distributions of gear surface after processing under different cutting conditions was given out, based on which a cause-effect study was carried out about the correlation between cutting parameters and the stress distribution, leading to methods of maintaining a low-stress condition during manufacturing.
