补充资料：包钢无缝钢管收集装置降噪和防冲击研究
包钢无缝钢管厂作为国家大型骨干企业，面临着激烈的市场竞争，因此在保有原有优势的基础上，迫切需要全面提升产品的质量，争取更大的市场份额。包钢无缝钢管厂的设备是五十年代从前苏联引进的，主要生产直径140mm至直径426mm的无缝钢管。在收集过程中，钢管的落差大，产生了噪音和冲击 。冲击使钢管发生了塑性变形，噪音损害了工人的身体健康。作为面向二十一世纪的现代化企业，必须考虑如何在优质高效生产的前提下，创造一个清洁、无污染的生产环境。因此，对于无缝钢管收集装置的深入研究势在必行。 | ||

使用ANSYS软件进行无缝钢管的变形模拟，其数据真实性得到了现场的认可，且在获得数据的同时并未影响生产。模拟的最终结果为新型无缝钢管收集装置的设计提供了理论依据，目前依据这一模拟结果设计的第一种方案已完成，正在进行第二种方案的设计。 | ||
