The invention discloses a vibration control system with a function of null adaptive tracking, and the system comprises a vibrating table driver; a vibrating table; and a displacement sensor. The output end of the vibrating table driver is connected with the control end of the vibrating table. The displacement sensor is disposed on the vibrating table, and the signal output end of the displacement sensor is connected with the vibrating table driver. Compared with the prior art, the system solves a problem of null offset in a mode of electrical automatic control, can automatically adjust the null point of the vibrating table, and achieves automatic matching of different test parts. Compared with a mode of manual adjustment, the mode employed by the system is simple in operation, is flexible in use, and is stable and reliable. Meanwhile, the system can automatically track and adjust the null point of a vibration system, thereby improving the accuracy and performance of dynamic response of a vibration testing system.
Description
technical field [0001] The invention relates to the technical field of vibration control, in particular to a vibration control system with a zero position self-adaptive tracking function. Background technique [0002] Vibration test refers to the test to assess the anti-vibration ability of the product in the expected use environment on the object or model subjected to vibration, which can simulate the impact of various vibration environments suffered by the product in the transportation, installation and test environments. Vibration tests were first applied in the aerospace field since the 1940s. With the development of modern science and technology, vibration tests have been widely extended to many industrial fields such as power machinery, transportation, and construction. [0003] The vibration test control system is mainly composed of a vibration table, a power amplifier, a controller, a sensor, a test piece and a fixture. According to the excitation method, the vibrat...
