CH3杆式小量程应变天平的研制

Development of a CH3 Bar Type High Sensitive and Small Measuring Span Strain Balance

将应变天平用于站台人体模型测力，并为此研制了人体五分量天平。文中给出了设计原理、静校公式及动校与实测结果，表明设计合理，可用于相应的试验研究。

A bar type high sensitive small measuring span strain balance is developed.The design principle,static and dynamic calibrations as well as the exporimental results of this newly developed 5-scale balnace for the measuring of shock wave force on human body model are given in this paper.The practical results show that the equipment is successful both in design and manufacturing and can be used in wind tunnel and other related experiment researches.
