Abstract

The results of applications of various methods for measuring the parameters of high-speed loading using a strain gauge, a fiber Bragg grating located on a metal measuring rod and an interferometer monitoring the movement of the free boundary of the end of the rod are presented. Numerical simulation confirmed the adequacy of the description of the shock-wave process according to experimental data and showed that, with the thickness of the adhesive layer fixing the fiber Bragg grating and the strain gauge on a dimensional rod up to 100 µm, the deformation parameters of the sensors correspond to the parameters of the stress-strain state of the rod. Experimentally, a good correspondence of the results of measuring the magnitude of the relative deformation at a pulse duration of 10-100 µs using sensors of various types is shown, and an estimate of the limit values of the measured values of the deformation wave parameters is given.

摘要

给出了使用应变片、位于金属测量杆上的光纤布拉格光栅以及监测杆端自由边界运动的干涉仪来测量高速加载参数的各种方法的应用结果。数值模拟根据实验数据证实了对冲击波过程描述的充分性，并表明，当在尺寸杆上固定光纤布拉格光栅和应变片的粘合剂层厚度达到100μm时，传感器的变形参数与杆的应力应变状态参数相对应。实验表明，使用各种类型的传感器在脉冲持续时间为10 - 100μs时测量相对变形量的结果具有良好的一致性，并给出了变形波参数测量值极限的估计。
