首先,概述了以不改变全尺寸静特性实验台整体结构为前提,在原有实验台上添加激振装置和测试仪器,增加动特性测试功能的必要和可能性.其次,概述了脉冲激励、振动测量、数据采集记录及动特性识别的基本原理.最后,将测量结果与理论计算作了比较,并讨论了可能产生误差的各种原因. First of all, the necessity and possibility of increasing the dynamic characteristic test function by adding the excitation device and the test instrument to the original experiment platform are summarized, on the premise of not changing the overall structure of the full-scale static characteristic test bench.Secondly, the influences of pulse excitation, vibration Measurement, data acquisition and recording and the identification of dynamic characteristics.Finally, the measurement results are compared with the theoretical calculations and the reasons for possible errors are discussed.
