The front fork shock absorber durability testing machine is a high-precision fatigue life testing device specifically designed for the shock absorption systems of bicycles, motorcycles, electric scooters, and other vehicles. By simulating the complex conditions such as bumps, impacts, and high-frequency vibrations during real riding, it comprehensively verifies the damping performance, rebound efficiency, sealing durability, and structural strength of shock absorbers. This equipment is widely used in shock absorber manufacturing, vehicle assembly lines, R&D laboratories, and third-party certification institutions to ensure that products meet international standards such as ISO 4210, ASTM F2042, and EN 14766, providing a scientific guarantee for the reliability and user experience of shock absorption systems.
Application scope
It is suitable for the durability inspection and testing of shock absorbers in the front forks of scooters.
Core functional modules
Dynamic Load Testing
Multi-axis Vibration Simulation: Vertical loading force (0~20kN), horizontal torque (±50N·m), replicating road conditions such as gravel roads, speed bumps, and jump impacts.
High-frequency Fatigue Testing: Set vibration frequency (1~50Hz), with cycle count ≥ 1 million times, to detect failure risks such as spring fatigue, oil seal leakage, and damping attenuation.
Temperature Coupling Testing: Optional temperature control module (-40℃~+120℃) to verify the stability of shock absorption performance under extreme temperatures.
Intelligent Monitoring and Diagnosis
Real-time Data Acquisition: Monitor damping force (accuracy ±1% FS), displacement (±0.01mm), temperature (±0.5℃), and vibration spectrum, generating force-displacement curves and life prediction models.
Failure Warning: AI algorithms analyze damping force fluctuations and abnormal noise characteristics to predict oil leakage or spring breakage and automatically shut down.
3D Motion Analysis: Optional laser displacement sensors capture the dynamic deformation of shock absorbers, generating 3D motion trajectory maps.
Environmental Adaptability Testing
Salt Spray Corrosion Testing: Simulate coastal or winter de-icing agent environments according to ASTM B117 standards to verify the anti-rust ability of metal parts.
Mud and Water Splash Testing: A spray system simulates muddy roads to test the wear of shock absorber dust covers and their sealing performance.
