Abstract

The invention discloses an ANSYS finite element platform-based prediction method for induction quenching hardening layer depth. The method comprises the following steps: (1) determining an actual working environment in induction quenching according to the technical requirements of a work-piece; (b) building a finite element entity model of an actual induction quenching environment on an ANSYS finite element platform according to the actual working environment; (c) firstly defining a PLANE13 attribute of a two-dimensional coupled field entity unit, defining material attributes, and then dividing to form proper finite element grids; (d) exerting a heat source load, a heat convection constraint and boundary conditions to each node of the two-dimensional coupled field entity unit PLANE13, carrying out electromagnetic heat coupling analysis on the work-piece by adopting a direct method to obtain an electromagnetic heat coupling calculation result; (e) calculating and analyzing a work-piece temperature field. According to the ANSYS finite element platform-based prediction method, the model, the load and constraint conditions can be modified according to the actual work-piece size and equipment parameters, the induction quenching test workload of the work-piece is greatly reduced, the analysis efficiency and the technical parameter test accuracy are improved, and the test cost is reduced.

Description

technical field [0001] The invention relates to a method for predicting the depth of a hardened layer by induction quenching, in particular to a method for predicting the depth of a hardened layer by induction quenching based on the ANSYS finite element platform. Background technique [0002] At present, induction hardening heat treatment has the characteristics of high quality, reproducibility and strong adaptability. It is one of the most widely used and fastest-growing surface treatment processes in the heat treatment industry. The finite element analysis of it can predict the hardened layer of induction hardened workpieces Depth, determine optimal process parameters and guide production. [0003] In order to meet the required surface hardness and hardened layer depth, size, structure and other requirements, it is necessary to strictly control the parameters of the heating, cooling and tempering process in the induction hardening process. [0004] The traditional materia...
