The Implementation of Automatic Test for the Dynamic Parameters of Model Foundation with Variable Disturbance

If the test for dynamic parameters of model foundation with variable disturbance adopts manual methods to control the test process, collect vibration waveforms, and process the test data, the work efficiency is low and the labor intensity is large. Composed of a notebook computer and a data acquisition card, the automatic test instrument of the model foundation dynamic parameter with variable disturbance based on the virtual instrument scheme was provided. This instrument could control the vibration frequency of the mechanical exciter by controlling the frequency converter, and the vibration signal of the model foundation can be automatically collected according to the program setting, so as to realize the automation of the test process. The automatic test instrument have a simple device, and have advantages of highwork efficiency, high precision and good reliability, making the process of testing simple and efficient.
