本文采用状态变量法,以突加正弦与突加余弦振动为作用函数,按通常701型和101型拾振仪使用的参数对动圈式位移摆拾振仪进行了动态分析。文中分析了动圈两端引入并联电容和不引入并联电容及引入并联电容同时又引入积分环节三种情况。这三种情况都给出了供修正实测记录直接查证用的前五个峰值的频率特性和峰值出现的时间特性,同时给出机械系统放大倍数随频率变化的特性。还给出了实际标定特性以及应用实例。
In this paper, the state variable method is adopted, and the effect of sudden plus cosine and sudden cosine oscillation is taken as the function. According to the parameters commonly used in Model 701 and Model 101, dynamic analysis is carried out. In this paper, the analysis of the moving coil at both ends of the introduction of parallel capacitors and does not introduce parallel capacitors and the introduction of shunt capacitors at the same time introduce the integration of three cases. All three cases give the frequency characteristics and peak time characteristics of the first five peaks for direct verification of the corrected measured recordings. The magnification of the mechanical system is also given as a function of frequency. Also gives the actual calibration characteristics and application examples.
