摘要
文中介绍了新研制的便携式高精度多功能拾振器的技术性能、工作原理和理论计算,分析讨论了仪器的特点,给出了技术指标实测结果并进行了结构微振动记录幅值谱分析。
A new compact multi-functional pick-up instrument with high precision is studied and produced. The technical performance and working principle as well as theoretical calculation of the instrument are presented. The characteristic of the instrument is discussed. The technical specification is measured actually. The amplitude Fourier spectrum of the structural vibration record is obtained.
