一、“轻结构”的概念大约30年以前,机车车辆轻结构研究会引用了“轻结构”概念,并拟定了相应的建议。这个概念被用来表征一定的结构原则,而术语是由飞机制造业借用来的,因为该行业中由于大量使用轻合金而经常使用这一术语。这个原则的定义是:在结构中只使用最少量的性能适应结构用途需要的材料,那么该结构可称之为轻结构。二、轻结构的采用轻结构的采用有时是出于技术原因,更经常地是出于经济原因。当必须制造其重量 First, the concept of “light structure” About 30 years ago, the study of the light structure of rolling stock quoted the concept of “light structure” and formulated the corresponding suggestions. This notion is used to characterize certain structural principles, while terminology is borrowed from the aircraft manufacturing industry because the term is often used in this industry because of the heavy use of light alloys. This principle is defined as a structure that uses only the minimum amount of material that meets the needs of the structure for its performance, so it can be called a light structure. Second, the use of light structure The use of light structure is sometimes for technical reasons, more often for economic reasons. When it must be made its weight
