The signal source through the vibration chamber is output to the power amplifier. After the signal is amplified, it is input into the vibrating table body to generate an excitation source. The vertical vibration test was carried out to simulate the actual situation of the specimen. The acceleration sensor signal is collected and inputted to the vibration control device. The output and feedback signals are superimposed and calculated. It can achieve a high overlap between the excitation source and the target spectrum. The signal target spectrum allows the system to complete the specimen’s vibration test. It can test the specimen’s vibration durability and integrity.
