Vibration monitoring can detect and issue alarms and protection information early, so that the machine can run safely, the operating life is extended, and the maintenance cycle of the unit is shortened.

[0003] As a very important testing method, vibration test bearing device is widely used in the manufacturing industry. Its main purpose is to detect the reliability and bearing capacity of the product by simulating the vibration impact conditions in the relevant environment.

Therefore, the data obtained from the vibration impact test may be difficult to reflect the actual situation, which will bring great difficulties to product design and manufacturing. Therefore, it is necessary to design a new technical solution to solve it. Utility Model Content
