【摘要】 硫化罐卡箍、齿啮式快开装置属于快开门式压力容器重要的非标准部件,由于结构复杂,使得硫化罐、齿啮式快开门压力容器的品质是过程参数、材料机械性能参数和结构尺寸的多变量、高度非线性的复杂函数,导致其结构设计至今仍属于经验试差的黑箱操作设计过程,如何建立其科学的设计方法是工程中急待解决的技术难题,而解决这一工程技术难题的的理论前提是研究建立非常规过程装备的智能优化自动化设计理论,然而至今国内相关研究罕见报道,为此开展过程装备智能优化自动化理论的研究具有重要的理论研究价值和工程应用价值。本文基于智能优化理论,研究建立了非常规过程装备的计算机协同集成智能优化自动化设计理论和技术,为我国过程装备设计技术与理论的突破奠定了科学的理论基础,主要取得如下成果:利用PROE的参数化语言,编写了过程装备自动化三维结构设计程序,实现了过程装备三维结构设计的自动化。利用ANSYS的APDL参数化设计语言,编写了过程装备的有限元应力分析自动化的程序,实现了应力分析和应力结果参数化提取的自动化。基于三维设计软件PROE、有限元分析软件ANSYS和多学科优化软件iSIGHT,研究建立了过程装备的三维结构设计、结构的有限元分析和智能结构优化的计算机协同集成自动化设计方法和理论,并在此基础上创建立了过程装备计算机协同集成智能优化技术平台,解决了软件之间的数据通信技术问题和设计过程自动化的技术问题。研究建立了基于多岛遗传算法的过程装备智能优化设计理论和方法。基于上述研究成果,对平推式硫化罐卡箍和DN 1200齿啮式蒸压罐进行了应力和质量智能优化分析,优化后的尺寸系列在满足强度条件下,硫化罐卡箍的最大应力可降低25%以上。其质量更是可以减轻50%以上。齿啮式快开门压力容器法兰的最大应力可降低10%以上。其质量也可以减轻10%以上,取得了明显的经济效益。

【Abstract】 Both the clamp connections of horizontal push vulcanizing boiler and the tooth-locked quick closure device of tooth-locked quick closure pressure vessel are the important non-standard components of process equipment.Because of Complex structures, the quality of a horizontal push vulcanizing boiler and a tooth-locked quick closure pressure vessel is the highly nonlinear multivariable complex function about process parameters material mechanical parameters and structural sizes which results in structural design so far is still a black box experience trial and error design process for process equipment. How to establish the scientific method is the technical problems need to be solved for engineering design.The theoretical premise of solving the engineering problems is to study the establishment of non-conventional automation intelligent optimizating design theory of process equipment. However, rare domestic related research has reported which makes researchs on Intelligent automated optimizating theoretical for process equipment have important theoretical research value and engineering value. Based on Intelligent optimizating theory, the theory and technology of computer collaborative integrated intelligent optimizating design automation is established for non-conventiona process equipment in this paper which lays the science theoretical foundation for China’s breakthrough technology and theory of process equipment design. and the main results are as follows:The procedures of three dimensional structural automatic design is wrote by measns of PROE parametric language and the automation design of three-dimensional structure of process equipment is realized. the procedures of finite element automatic stress analysis are compiled by ANSYS APDL language for process equipment, the stress analysis automation and automated extraction of stress results are achieved.Based on three dimensional design software PROE, finite element analysis software ANSYS and multidisciplinary optimization software ESIGHT, the theory and method of computer collaborative integrated intelligent optimizating design automation is established for non-conventiona process equipment, the technological platform of computer collaborative integrated intelligent optimizating design automation is created for non-conventiona process equipment, the technical problems of the software data communication and design process automation were solved, the process equipment intelligent optimization design theory and method is also established based on the multi-island genetic algorithm.The stress and mass intelligent optimization analysis of horizontal push vulcanizing boiler and the DN 1200 tooth-locked quick closure pressure vessel are implemented based on above research results.Unde rthe satisfaction of strength conditions, the maximum stress of clamp connections reduce more than 25% and its mass can also reduce more than 50% after optimization,and the maximum stress of tooth-locked quick closure flange can reduce above 10% and its mass can also reduce above 10% after optimization. The better economic benefit is achived
