THE ARCHAEOLOGICAL VALUE OF ARROWS AND CROSSBOWS IN THE TANG DYNASTY AND ITS INFLUENCE ON THE STUDY OF MODERN COLD WEAPONS

Abstract

In order to excavate the archaeological value of cold weapons, the arrows and crossbows of the Tang Dynasty are taken as the research object. The metal material, external shape and oxide of the crossbow were observed by microscope, the internal composition of the crossbow was observed by infrared imager, and the mass distribution and other indicators were observed by the mechanical measuring instrument, and the research was carried out in combination with the network literature. The results show that the crossbow of the Tang Dynasty is mainly bronze, containing a small amount of lead, tin and other metals, with a surface hardness of 2.3~4.2Hb, and oxides such as lead oxide and iron oxide. Therefore, the Tang Dynasty arrow crossbow has the rationality of pneumatics and gravity in the design of arrows, and the content of tin, lead and other materials is reasonable, which has practical value, and promotes the development of modern cold weapon forging and pneumatic layout.
