摘要

本研究考察了一套振动导线伸长计，其中使用了范德波尔发生器来保持导线的自然振动。以这种方式激发，自激振动允许随时间不间断的应变测量，包括快速变化的应变以及混沌的自然应变。针对工业上常用的两种典型振动线规，分析了伸丝速度对其计量特性和适用性的影响。

THE APPLICATION OF SELF-EXCITED VIBRATIONS FOR DYNAMIC STRAIN MEASUREMENTS CARRIED OUT BY VIBRATING WIRE TENSOMETERS

This study examines the set of vibrating wire extensometer, in which to maintain natural vibrations of the wire Van der Pol generator has been used. Excited in this way, self-exited vibrations allow for uninterrupted strain measurements over time, including fast-changing strains as well as chaotic nature strains. For two typical vibrating wire gages used in the industry, the impact of the wire extension speed on its metrological characteristics and applicability has been analyzed.
