Project name: Modal test of Zoomlion erial ladder
Brief introduction：In the experiment, vibration modal parameters were measured using the principle of unmeasurable force. The use of water guns to inspire the ladder structure to generate vibrations. The DE-944 data acquisition system collects the response time signals of each measurement point. The self-power spectrum calculation is performed through the test signal. The modal parameter identification principle is used to identify the natural frequency, vibration mode and damping of the ladder.
