由国家地震局工程力学研究所科研人员杨学山、黄浩华、黄振平共同研制的“无源伺服式往复摆多功能拾振器”最近获得了国家实用新型专利。本专利是一种构思新颖的拾振器。它克服了国内通用电磁式低频拾振器在结构上的缺点,在最大幅值和使用频率范围方面大为扩展,可测工程振动领域0.5-100 The “passive servo reciprocating pendulum multi-functional vibration picker” jointly developed by researchers Yang Xueshan, Huang Haohua, and Huang Zhenping at the Institute of Engineering Mechanics of the State Seismological Bureau recently won the national utility model patent. This patent is a novel concept of vibration picker. It overcomes the shortcomings of the domestic general-purpose electromagnetic low-frequency vibration pickup in the structure, greatly expanded in the maximum amplitude and frequency range of use, measurable engineering vibration field of 0.5-100
