The influence of laser surface texturing on the transient frequency response of gears

To achieve parameterized modeling of gears, an involute spur cylindrical gear tooth model was established in Pro/E. Utilizing laser surface texturing and finite element theory, MSC. Nastran was employed to analyze the transient frequency response of both ordinary gears and laser surface-textured gears. Laser engraving technology was applied for surface texturing on the teeth. Both actual bench tests and finite element simulation results demonstrate that, under the same internal excitation, the response of ordinary gears differs from that of laser surface-textured gears. Notably, laser surface-textured gears exhibit the least deformation, effectively enhancing the fatigue performance of gears and bolstering their reliability.
