摘要
基于虚拟样机概念,采用Pro/E的二次开发参数化建模手段对内径为4000mm的超大型蒸压釜进行设计,运用Workbench对壁厚进行优化设计。依据相关标准规范,并考虑蒸压釜多支座和自重载荷的影响,对蒸压釜的应力状态进行分类与评定。结果表明:通过优化釜体计算厚度可减少2.27mm,釜体的材料消耗降低9.13%。采用这种参数化建模与优化的方法,对直径4500mm、5000mm、5500mm、6000mm的蒸压釜进行快速建模装配与优化设计。本研究方法可提高设计计算的效率,有效降低蒸压釜制造材料的消耗量。
Based on the concept of virtual prototype,the wall thickness of a super large autoclave with a diameter of 4000 mm designed by Pro/E parameterization was optimized by using Workbench. Meanwhile,according to the JB-4732-95（2005）,considering the influence of multi supports and gravity,the stress of autoclave was classified and evaluated. The results show：after optimization,the calculated thickness of autoclave could be reduced by 2.27 mm,and the total weight of autoclave could be decreased by 9.13%. By using this method,autoclaves with diameters of 4500 mm,5000mm,5500 mm and 6000 mm are modeled and optimized rapidly. It could reduce the consumption of autoclave manufacturing materials,and improve the efficiency of design calculation.
