Abstract
A method for improving the uniformity of connection performance of an assembly surface based on zoned hardening is provided. Through a finite element contact analysis of the assembly surface, a topology optimization of the hardening layer layout of the assembly surface is carried out with the aim of improving the uniformity of the connection performance of the assembly surface. The design is based on the optimized theoretical data, and uses the laser hardening technology to realize the zoned differential hardening of the assembly surface. By performing the zoned differential hardening on the assembly surface, the uniformity of the connection performance of the assembly surface can be effectively improved, and the purpose of improving the high cycle fatigue and the vibration of the high-end equipment parts such as aero-engines can be further achieved.
