Technical Field

The invention belongs to the technical field of auxiliary supports, and particularly relates to an auxiliary support.

Background

Along with the development of modern mechanical equipment towards the complicated structure and automation, the method for monitoring the operation state of the mechanical equipment and diagnosing whether the mechanical equipment has faults by adopting vibration signals is simple, feasible, accurate and reliable and can effectively reduce the loss.
