复杂陶瓷件烧结过程温度场数值模拟及仿真

随着陶瓷应用领域的不断扩展,对其品质要求也越来越高.而传统的设计工艺与制造过程是相分离的,到最终生产工艺的定型需要大量的反复修改.为解决传统陶瓷设计工艺只能依靠经验的现状,节约成本,缩短生产周期,故开发了复杂陶瓷零构件烧结过程计算机仿真软件.首先借助传热学原理来建立温度场模型,其次借助有限差分法处理温度场模型,编写出此仿真模拟软件的核心计算代码,从而实现了复杂陶瓷零件和组合构件烧结过程中温度场的模拟仿真.

Study on the simulation of the temperature field of sintering complex ceramics parts

As the applied fields of ceramics enlarged, the quality of the ceramics parts was needed higher and higher. However, the designing and the manufacturing of the ceramics parts were separated, and the designing resolution had to be amended many times before it became the final resolution. In order to solve the problem that designing ceramics parts has to depend on experience, to save the cost and to shorten the manufacturing time, the simulation software on the temperature field of sintering complex ceramics parts was developed. First, the formula of temperature field was founded on the basis of the diathermanous theory. Second, the Finite Difference Method was used to deal with the formula of temperature field and make the core code of this software for calculating, thus the simulation of the temperature field of sintering complex ceramics parts and combined component was realized.
