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.
