DR - Electric Scooter Handlebar Comprehensive Fatigue Testing Machine

The scooter handlebar comprehensive fatigue testing machine is a high-precision durability testing device specifically designed for the handlebar systems of electric and non-electric scooters. By simulating multi-dimensional force scenarios during riding (turning, twisting, vertical load), combined with high-frequency cyclic loading, environmental coupling, and impact tests, it comprehensively verifies the fatigue strength, reliability of welding points, material durability, and control stability of the handlebar structure, folding mechanism, and grip kit. This equipment is widely used in scooter manufacturing, quality inspection centers, R&D laboratories, and export certification fields to ensure that products comply with international safety standards such as CE EN 14619, CPSC 16 CFR Part 1500, and GB/T 17761, reducing the riding risks caused by handlebar failure.

Application scope

Designed to simulate the vertical vibration test standard of the scooter frame, the scooter frame is fixed on the fixture of this testing machine and subjected to fatigue loading of a certain frequency, load, and test cycle. 

Core functional modules 

Multi-dimensional Dynamic Loading Test

Steering Fatigue Test: Simulate high-frequency steering actions (±90°, frequency 1-10Hz), with a cycle count of ≥500,000 times, to detect welding cracks at the handlebar root and the risk of loosening of folding locks.

Vertical Load Test: Apply 0-1000N dynamic pressure (simulating the impact of human weight) to verify the handlebar's bending strength and deformation recovery capability.

Torsional Durability Test: ±30N·m torque cyclic loading to detect metal fatigue and thread slippage risks at the connection between the handlebar and the stem.

Environmental Coupling and Impact Test

Temperature and Humidity Simulation: Optional high and low-temperature chambers (-30°C to +80°C, humidity 10% to 95% RH) to verify the risk of plastic handlebar brittleness or metal structure deformation in extreme environments.

Impact Test: Simulate accidental impacts with an instantaneous impact force of 500N and a pulse width of 5ms to detect the risk of handlebar breakage.

Intelligent Monitoring and Diagnosis

Real-time Data Acquisition: Monitor torque (accuracy ±0.5% FS), displacement (±0.01mm), and strain (±0.5% FS), generating fatigue damage curves and life prediction models.

Abnormal Sound and Failure Warning: Acoustic sensors capture frictional abnormal sounds, and AI algorithms analyze torque fluctuation characteristics to predict crack risks and automatically stop the machine.

3D Deformation Analysis: (Optional) Laser scanner captures the expansion path of micro-cracks, generating a three-dimensional damage map.
