【摘要】：超高压管式反应器不但承担超高压力和极高的温度,而且承受反应温度和压力沿管长不断变化地冲击,随着工业发展需求的增大,管式反应器承受的压力要求越来越高。为提高超高压管式反应器的承载能力,普遍采用自增强技术。随着计算机技术的飞速发展,虚拟制造技术已经渗透到各个领域,特别是对传统的制造业造成了很大的影响,解放了大量的人力和物力,并提高了产品的可靠性和核心竞争力。超高压管式反应器自增强制造多采用液压生产系统,制造条件苛刻,不但超高压力,而且伴随着高危险性,配套附属设备同样要求条件严格,制造成本非常高。鉴于此,以超高压管式反应器自增强液压生产系统为研究对象,将虚拟制造技术引入到超高压管式反应器自增强处理的生产工艺中,构建了一套超高液压处理自增强加卸压系统平台,对各液压元件分别建模,并实施虚拟组装,确认了工艺的可行性。采用ANSYS Workbench有限元的方法对管式反应器自增强处理前后受载情况进行应力分析,仿真自增强处理工艺加载卸载的受力过程,并建立了分析结果的数据库。利用虚拟仪器软件Lab VIEW开发了超高压管式反应器自增强虚拟制造系统,与ANSYS Workbench软件分析结果的数据库相结合,实现虚拟制造的动态可视化结构。
[Abstract]:The ultra-high pressure tubular reactor not only bears the ultra-high pressure and extremely high temperature, but also withstands the reaction temperature and pressure constantly changing along the length of the tube. With the increasing demand of industrial development, The pressure of tubular reactor is higher and higher. In order to improve the load capacity of ultra-high pressure tubular reactor, self-reinforcement technology is widely used. With the rapid development of computer technology, virtual manufacturing technology has penetrated into various fields. Especially, it has a great influence on the traditional manufacturing industry, liberates a lot of manpower and material resources, and improves the reliability and core competitiveness of the products. The manufacturing conditions are harsh, not only ultra-high pressure, but also high risk. The auxiliary equipment is also required strictly and the manufacturing cost is very high. In view of this, the self-reinforced hydraulic production system of ultra-high pressure tubular reactor is taken as the research object. The virtual manufacturing technology is introduced into the production process of UHV tubular reactor self-reinforcement treatment, and a set of super-high hydraulic treatment self-reinforcement and pressure relief system platform is constructed, each hydraulic component is modeled, and virtual assembly is carried out. The feasibility of the process is confirmed. The stress analysis of the tubular reactor before and after self-strengthening treatment is carried out by using ANSYS Workbench finite element method, and the loading and unloading process of the self-enhanced treatment process is simulated. A virtual instrument software Lab VIEW is used to develop a self-enhanced virtual manufacturing system for ultra-high pressure tubular reactor. The dynamic visualization structure of virtual manufacturing is realized by combining with the database of analysis results of ANSYS Workbench software.
