金属龙骨按材质、使用场合、断面形状分类众多，不同类型龙骨的力学性能检测方法不一，检测装置各异。本文通过对国内外金属龙骨标准的力学性能检测方法进行分析，研制出一种符合多标准、多类型的多功能金属龙骨力学性能检测装置，并分析其可行性和操作特点。

Metal keels are classified into many categories based on material, usage, and cross-sectional shape. The mechanical performance testing methods and devices for different types of keels vary. In this paper, the mechanical performance testing methods of domestic and foreign metal keel standards are analyzed. A multi-functional testing device for metal keel mechanical performance is developed, which meets the requirements of different products in multiple standards. And its feasibility and operational characteristics are discussed.
