| 摘 要： | 开发了三维温度场计算程序，模拟了活塞铸件在不同界面换热系数下的金属型凝固进程，说明界面换热系数对金属型凝固速度影响很大，可作为调节金属型凝固的控制因素。同时还对比说明了相对计算的意义。 |

| Abstract: | D program for simulating temperature field was developed. The solidification process of piston casting in metal mold with different interface heat exchange coefficients( h ) was simulated. The results showed that the interface heat exchange coefficient has great effect on solidification rate in metal mold, and could be used as a control factor in adjusting solidification. And the significance of relevant calculation was expounded in comparison with practical pouring result. |
| Keywords: | Metal Mold Numerical Simulation Interface Heat Exchange Coefficien |
