The Fastener Lateral Vibration Testing Machine is designed for testing threaded fasteners. It represents the first independent research and development in China, with full intellectual property rights for both software and measurement and control systems. This innovation has helped break the reliance on imported equipment from abroad.

The lateral vibration tester can fully comply with standards such as GB/T 10431-2008 and DIN 65151, allowing for the detection of the self-locking performance (anti-loose performance) of fasteners under lateral dynamic loads at certain frequencies and amplitudes.

The process begins with an automatic tightening device that applies a set clamping force to the bolt or nut. Once the test starts, the machine applies a lateral dynamic load to the entire connection pair. Throughout the test, the system records and analyzes changes in axial force and loosening angle. With visual charts, users can clearly understand the self-locking performance and various technical parameters of bolts and nuts under vibration conditions.

Test Specifications: M6-M36 Bolt and Nut Test

Computer System: Composed of a work platform, Matsushita servo motor and reducer, high-precision load sensor, grating displacement sensor, loose angle photoelectric encoder, control and measurement system. A tightening torque sensor can be configured according to customer requirements to measure torque and total friction coefficient before testing. This provides scientific data for analyzing the relationship between bolting, locking performance, and friction coefficient.

Measurement and Control System: Designed with international industry-leading standards, aligned with ISO. It uses new materials, processes, and technologies. All units, instruments, and sensors follow international standards (IS). The device structure ensures sufficient static, dynamic, thermal stability, stiffness, and accuracy. The system features good dynamic quality, with components that are highly precise, reliable, and resistant to interference.

The measurement and control system adopts a bus template design, enabling standardized and templated functional unit design. It offers high measurement accuracy, flexible configuration, strong interchangeability, and easy after-sales support. Servo control uses advanced PID technology for precise control.

Software Function: Based on the Windows 7 operating system, the testing software ensures stable and efficient operation. Results can be exported to Office or PDF formats, making report generation and management simple and efficient.

Software Interface: Utilizes virtual instrument technology within a Windows environment. The user interface is intuitive and easy to operate. During the test, real-time display of test data and curves is provided. After the test, data processing can be completed, and a full test report can be printed. The results and curves are stored in a database format for easy retrieval and analysis.

This testing machine is primarily used to evaluate the self-locking performance of threaded fasteners under lateral dynamic loads with specific frequency and displacement. It allows users to analyze the pre-tightening axial force curve, lateral displacement, and vibration period to determine the anti-loosening characteristics of threaded fasteners. It also helps study the self-locking and optimal locking behavior of thread fastening systems in mechanical structures.

The standard test machine is designed according to DIN 65151. Since the test and analysis software allows users to freely edit, the machine can meet multiple testing standards simultaneously, provided the hardware conditions are met. It is also compatible with domestic GBT10431 standards.
