gauge length

The optimization of tension Hopkinson bar ( TSHB) tests has been studied. The structure and loading conditions of TSHB have evident influence on test results including the gauge length and geometry of specimen, interconnecting linkage, contact boundary, stress waves and so on.

研究了拉伸Hopkinson试验（TSHB）的优化问题：Hopkinson拉伸试验装置的结构及加载条件明显影响试验结果，其中包括试件的几何形状、试件与杆的连接以及接触边界、应力波的影响。

The authors designed a kind of improved control system based on the theoretical relation among the initial gauge length of sample, travel rate of testing machine transom, time and sample's real constant-strain rate.

根据试样初始标距长度、试验机横梁移动速度、试样真实恒应变速率和时间的理论关系式，设计了改进的控制系统。

There is a fixed relationship between the gauge length and the cross-sectional area of the test-piece at the reduced diameter.

定向低频分析与测距浮标标距长度和试样在直径减少处的横截面面积之间有固定的关系。
