吊装机械工程Bromma：吊具的结构寿命评估

点击上面蓝字
One such project is Varilight (Reduced VARIation in the manufacturing processes enabling LIGHTweight welded structures) in collaboration with KTH - [the Swedish] Royal Institute of Technology, in Stockholm - and several industrial and academic partners. A box-welded structure - a common component in spreaders - has been investigated within the project.
The White Paper is co-authored by Dr Mansoor Khurshid, Head of Structural Science at Bromma and Lars Meurling, the company’s VP EMEA & Marketing.
Bromma说：“该白皮书介绍了如何在起重机吊具上应用复杂钢结构是起重机的寿命评估方法，以及该结果如何与现实联系起来。Bromma参与了行业支持是起重机的学术研究项目，从而获得了综合性结果在这些项目中。”
Spreader manufacturer Bromma has released a new "White Paper" on the evolution of scientific methods for structural life assessment and its application for lightweight spreader design.

The main findings of the research indicate that when more advanced calculation methods are applied, the outcome is more in line with reality. By applying the more advanced methods - even though applicable standards are less stringent – manufacturers of lifting equipment can lead the development towards more durable and also potentially safer steel structures and products.
这样的项目之一就是与斯德哥尔摩皇家瑞典技术学院KTH以及多家工业和学术合作伙伴合作的Varilight（降低了制造过程中的轻度变化，使轻型焊接结构成为可能）。在该项目中，对箱式焊接结构（吊具中的常见组件）进行了研究。
The White Paper includes results from fatigue strength tests performed on box welded structures. The results show that there is a significant difference in the precision of different fatigue strength evaluation methodologies, when applied on complex welded joints in crane spreaders.
研究的主要发现表明，如果使用更高级的计算方法，则结果与实际情况更加吻合。通过采用更先进的方法-即使适用的标准不太严格-起重机械制造商也可以引领开发向更耐用，也可能更安全的钢结构和产品发展。
白皮书包括对箱式焊接结构进行疲劳强度测试的结果。结果表明，将不同疲劳强度评估方法应用于起重机吊具的复杂焊接接头时，其精度存在显着差异。
