摘要/Abstract

摘要： 针对20CrMnTi齿毂高压气淬工艺设计的需求,建立了一套流场-温度场-组织场-应力应变场耦合模拟体系,能够实现对淬火气流与工件的同步耦合计算。利用该体系模拟了不同淬火气压和进气方式下的齿毂高压气淬过程,分析了不同工艺方案下齿毂的组织成分、硬度以及畸变,确定了2.0 MPa、下方单向进气的工艺方案,模拟结果满足齿毂性能要求。

Abstract: According to the requirements of process design of high-pressure gas quenching for 20CrMnTi gear hub, a coupling simulation system of the flow field, temperature field, phase field and stress-strain field was established, which can realize the synchronous coupling calculation of the quenching gas flow and workpiece. Using this system, the high-pressure gas quenching process of gear hub under different quenching gas pressures and gas blowing modes was simulated. By analyzing the microstructure, hardness and distortion of the gear hub under different process schemes, an optimum process scheme of 2.0 MPa and lower unidirectional blowing is proposed, and the simulation results meet the performance requirements of the gear hub.

Key words: multi-field coupling, numerical simulation, high-pressure gas quenching, synchronizer gear hub
