可加工陶瓷结构件的设计优化研究

以云母微晶玻璃陶瓷为研究对象，通过模拟和分析，设计了一种金属热防护系统承力结构件，对可加工陶瓷的结构件进行了优化设计；对可加工陶瓷结构件在热、力载荷以及热力耦合下的陶瓷承力件的热流、温度以及应力的分布进行了分析。通过优化调整结构件的形状，最大应力值分别降低了14．8％和30．64％，最大热流值分别降低了7．65％和6．73％。分析表明，此种模拟方法，能够直观的考察结构件内部在各种载荷下的参数分布，并通过优化，可获得理想的结果。

Design Optimization of Structural Part of Machinable Glass Ceramics

Through simulation and analysis, design optimization to a strength structural part made of mica microcrystal glass ceramics had been studied. Through the analysis of the thermal flux and the temperature as well as the stress distribution of the machinable ceramic structural part under the thermal and strength load, the shape of structural part had been adjusted. The result showed, by the adjustment, the maximum stress reduced by 14.8% and 30.64% respectively, the most greatly thermal flux reduced by 7.65% and 6.73% respectively. It had been indicated that this optimized method could inspect parameter distribution of structural part under loads, and the ideal result could be obtained;
