1. 毕业设计(论文)的内容和要求
材料在高温下的剩余寿命受到温度和应力的共同影响,为了准确预测某厂蒸汽转化炉 H1201服役炉管的剩余寿命,建立转化炉一排炉管的有限元模型(含44根炉管和1根集气管),考虑恒力吊架和集气管约束,对管系的热应力和热变形以及蠕变应力和蠕变变形行为进行模拟,获得长期服役后转化炉 H1201管系的受力和变形情况,为炉管的寿命预测提供准确的载荷参数。
要求学生主要完成以下工作:①阅读文献30篇以上,其中英文8篇以上;②英文翻译(3000字以上):1篇;③开题报告:1份;④实习报告:1份;⑤毕业论文:1篇;⑥图纸要求:CAD图纸不少于3张A1。
论文要求条理清楚,文句通顺,图文并茂,层次分明。
