The front fork vibration and impact testing machine is mainly used to simulate the fatigue performance test of the front fork of bicycles, electric bikes and other vehicles under horizontal vibration and impact loads. By setting specific frequencies, amplitudes and impact forces, it detects the deformation, fracture and other failure conditions of the front fork after repeated vibration or impact. It is suitable for R&D, quality inspection and production verification stages. The core functions include multi-directional vibration control, impact force adjustment and automatic shutdown protection.
Key Features & Advantages of the Online front fork testing machine
Dynamic Load Testing
✦ Multi-axis loading simulation: Vertical load range 0 to 20 kN (accuracy ±0.5% full scale), lateral torque range 0 to 500 Nm (accuracy ±1% full scale), simulating the combined forces of impact, steering and braking during cycling.
✦ Fatigue life testing: Cycle count ≥1 million times (frequency 1 to 10 Hz), detecting risks such as weld cracking and material fatigue in the front fork.
Rigidity and deformation analysis
✦ Static rigidity testing: Vertical rigidity measurement accuracy ±0.1 mm/kN, torsional rigidity measurement accuracy ±0.1°/Nm, dynamic display of stress-strain curves.
High-speed camera monitoring (optional): 1000 frames per second high-speed camera captures micro deformations, laser displacement sensor (accuracy ±0.01 mm) records real-time displacement.
Environmental coupling testing (optional)
✦ Temperature and humidity simulation: Temperature range -30°C to +60°C (accuracy ±1°C), humidity 10% to 95% relative humidity, verifying the performance degradation of materials under extreme conditions.
✦ Salt spray corrosion testing: Compliant with ASTM B117 standard, testing the corrosion resistance of the front fork's surface coating and metal components.
Intelligent data management
✦ Real-time data acquisition: Synchronous recording of multiple parameters such as load, displacement, temperature, and vibration, data storage ≥100 million records.
One-click report generation: Export reports in PDF/Excel format (including fatigue life curves, SPC statistical charts), supporting integration with MES/ERP systems.

Using the Derui Online Front Fork Testing Machine is straightforward and seamlessly integrates into your production flow. Here’s how it works:
Specimen Loading: An operator or automated system securely mounts the front fork onto the machine's test fixture, which typically holds the fork by its steerer tube and dropouts.
Parameter Selection: The operator selects the appropriate test program via the PLC touch-screen (e.g., "Model X Functional Test"). Parameters like compression speed, stroke length, and target cycle count are pre-set.
Automated Test Execution: The machine initiates the test, driving the actuation mechanism to compress and release the fork. It simulates real-world forces and movement patterns.
Real-Time Data Acquisition: Throughout the cycle, high-precision load cells and displacement sensors continuously measure force and position. The system analyzes the data to create a real-time force-displacement curve.
Performance Analysis & Pass/Fail Decision: The software compares the live data against pre-defined tolerance windows for key parameters like compression damping force, rebound damping force, and overall smoothness. The system instantly determines if the fork passes or fails.
Immediate Result Communication: A clear visual signal (e.g., green/red light stack) and on-screen message inform the operator of the result, allowing for immediate action—sending the fork to the next assembly stage or to a rework bin.
Data Logging & Traceability: All test results, including force-displacement curves for failed units, are automatically saved. This data can be linked to the specific unit for full traceability and used for statistical process control (SPC).
This blend of precise actuation, real-time monitoring, and instant analysis ensures every front fork leaving your line meets your exacting quality standards.
