摘要/Abstract

摘要：

热态轴类锻件内部温度场分布特征对锻件内部空洞检测起着重大作用。针对该问题，在传热学理论的基础上建立了热态轴类含空洞锻件的二维非稳态传热模型。首先利用集总参数法获得该模型的内部边界条件。然后通过红外热像仪采集得到该模型的初始温度条件，结合分离变量法求解该模型，从而获得含空洞锻件的内部温度场分布。最后通过实验分析了不同空洞尺寸条件下锻件内部温度场的分布特征。

Abstract:

For hot axial void forgings, interior temperature field distribution plays a key role in the detection of inner void defect. Aiming at the issue, a two-dimensional unsteady heat transfer model of the forgings with void was established based on the heat transfer theory. Firstly, interior boundary conditions of the model were obtained by using lumped parameter method. Secondly, the initial temperature conditions of the model were collected by the thermal infrared imager. The interior temperature field distribution of forgings with void was acquired by separation variable method. Finally, interior temperature field distribution characteristics of forgings under different void size conditions were analyzed according to the experimental results.

Key words: void detection, two-dimensional unsteady heat transfer, interior temperature field, hot axial forgings
