The Fastener Lateral Vibration Testing Machine is designed for threaded fasteners, offering comprehensive analysis of their performance under dynamic loads. This is the first independently developed system in China, with full intellectual property rights in both software and measurement control systems, breaking the dependency on imported equipment.

The lateral vibration tester follows standards such as GB/T 10431-2008 and DIN 65151 to evaluate the self-locking (anti-loose) performance of fasteners under lateral vibrations of specific frequency and amplitude. The process starts with an automatic tightening device that sets the clamping force precisely. Once the bolt or nut is tightened, the machine applies a controlled lateral load to the entire connection pair.

Throughout the test, the system continuously records and analyzes changes in axial force and loosening angle. With detailed charts, users can clearly assess the self-locking capability and other technical parameters of the fastener under vibration conditions.

Test Specifications: M6-M36 bolts and nuts.

Computer System: Comprising a work platform, Matsushita servo motor and reducer, high-precision load sensor, grating displacement sensor, photoelectric encoder for measuring looseness angle, and a control and measurement system. Additional torque sensors can be configured based on customer needs, enabling the acquisition of torque and total friction coefficient before testing.

This system provides essential scientific data for analyzing the relationship between bolting, locking performance, and friction coefficients.

Measurement and Control System: Designed with international industry-leading standards, aligned with ISO requirements. It uses advanced materials, processes, and technologies, ensuring all units, instruments, and sensors comply with international standards (IS). The device structure ensures sufficient static, dynamic, and thermal stability, along with high accuracy and reliability. Components are selected for precision, durability, and strong anti-interference capabilities.

The system adopts a bus template design, allowing for standardized functional unit configurations, high accuracy, flexible setup, and easy maintenance. Servo control utilizes PID technology for precise and stable operation.

Software Function: Based on the Windows 7 operating system, this testing software ensures stable and efficient performance. Results can be exported in Office or PDF formats, making it easy to generate and manage reports.

Software Interface: Utilizes virtual instrument technology within a Windows environment, offering a user-friendly interface that’s simple to operate. During testing, real-time data and curves are displayed, and after the test, data processing and report printing can be completed. All 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 set frequency and displacement. It helps analyze the pre-tightening axial force, lateral displacement, and vibration period curves to determine anti-loosening characteristics. It supports research into the self-locking and optimal locking features of thread fastening systems in mechanical structures.

The standard test machine complies with DIN 65151. With customizable software, the machine can meet various testing standards as long as the hardware allows. It also supports domestic GBT10431 testing requirements.
