The analysis and detection for signals of bearing vibration could judge whether rolling bearing has defects or not. However, most of the domestic bearing manufacturers still rely on speed bearing vibration measuring instrument and experience (the human hearing and display of observer) to realize the fault diagnosis of rolling bearing, which undoubtedly makes a low detection on the efficiency and accuracy. Aiming at the shortcomings of study of the domestic test method on bearing vibration, a full-automatic test system of bearing vibration is designed. The test system was introduced in three aspects: hardware design, software design and control system. Experimental verification shows that the system works efficiently and satisfies the requirements of industrial field.
