摘要
本文给出哈尔滨国家地震局工程力学研究所制造的中国力平衡加速度计(RJL-1)的理论和实验分析。研究发现,此传感器的传递函数与美国的力平衡加速度计(FBA-1)相同。同时观察到,用单自由度粘滞阻尼体系表示感传器的反应,对于接近于和高于自振频率的频率是不适当的。
Theoretical and experimental analyses of Chinese Force Balance Accele-rometer (RJL-1),manufactured by the Institute of Engineering Mechanics,SSB in Harbin,are presented.It is found that the transfer function of this transducer is identical to the American Force Balance Accelerometer (FBA-1).It is also observed that the representation of the transducer response by means of a single degree of freedom viscously damped system for frequencies near and higher than its natural frequency,is not adequate.
