Test analysis studies. The first independent research and development in China, software and measurement and control systems are completely independent intellectual property rights, breaking the situation of relying on imported equipment abroad.

The transverse vibration tester can be completely followed

,

Lateral vibration test standard to detect the self-locking performance (anti-loose performance) of fasteners under lateral dynamic loads of a certain frequency and amplitude. First, the servo automatic tightening device automatically tightens the bolt to be tested according to the set clamping force.

Nut. Then, the test is started and the test machine will apply a lateral dynamic load of a certain frequency and amplitude to the entire connection pair. Throughout the test, the system will record and analyze changes in the axial and loose angles of the fastener. With the relevant charts, you can clearly understand the bolts

Self-locking performance (anti-loose performance) and various technical parameters of the nut under vibration.

software interface

Adopt virtual instrument technology in Windows environment. The man-machine interface is friendly and easy to operate. During the test, the test data and test curve are displayed in real time; after the test is completed, the corresponding data processing can be completed, and the complete test report can be printed. The test results and test curves are stored in a database format for easy query of test results.

The testing machine is mainly used to detect the self-locking performance (anti-loose performance) of the threaded fastener under the lateral dynamic load to which a certain frequency and displacement are applied. One can use the test machine to analyze the curve of the pre-tightening axial force, the lateral displacement and the lateral vibration period to determine the anti-loosening characteristics of the threaded fastener; in order to study the self-locking and optimal locking of the thread fastening system in the mechanical structure characteristic. The standard test machine is designed in accordance with DIN 65151. Since the test/analysis software has the characteristics that users can freely edit, the test machine can meet the test requirements of various standards at the same time under the condition that the hardware conditions of the device are satisfied. The test machine can meet the test requirements of the domestic GBT10431 standard.
