摘要:
应用数值模拟技术对双金属复合过程中的非稳态温度场进行计算.由于外材和芯材在凝固过程温度变化的不同特点,选择不同的权系数计算温度.同时,在温度的计算中,考虑了双金属复合结合界面热阻、凝固过程中释放潜热以及导热系数等各方面因素的影响.通过热电耦对不同位置的温度值进行采集,将采集到的温度曲线和模拟的温度曲线进行对比,结果表明模拟的温度曲线比较能够反映实际温度的变化.
Abstract:
Numerical simulation was applied to calculate the unsteady state temperature field in the process of bimetallic compositation. Due to the different characteristics of temperature changes of the outer material and the core material in the solidification process, different weight coefficients are selected to calculate the temperature. At the same time, in the calculation of temperature, the influence of various factors such as thermal resistance of bimetallic composite bonding interface, latent heat release during solidification process, and thermal conductivity are considered. The temperature values at different locations are collected by thermocoupled, and the collected temperature curves are compared with the simulated temperature curves, and the results show that the simulated temperature curves can reflect the actual temperature changes.
