Bicycle Dynamic Durability Tester
The Bicycle Dynamic Durability Tester is designed to simulate the periodic loads and road impacts encountered during real-world cycling. Combining drum-driven rolling with bump impact, the machine conducts long-term dynamic fatigue testing on complete bicycles under specified load and speed conditions. It evaluates frame strength, assembly reliability, and the durability of key components, making it ideal for type testing, quality control, and R&D validation of bicycles.

Test Principle
The bicycle is fixed on the test frame, with front and rear wheels loaded with specified weights. The drum drives the wheels at a set speed while bump structures on the drum surface generate periodic vertical impact loads. Over long-term cyclic loading, the machine applies repeated fatigue stress to the frame, suspension system, wheel assemblies, and joints, providing a comprehensive evaluation of bicycle durability and structural reliability under real-use conditions.
Operation Instructions
(1) Select and fix the appropriate loading weights according to the testing standard.
(2) Install the bicycle on the test frame, adjust wheelbase, and secure front and rear wheels.
(3) Verify bump assembly installation and safety protection devices.
(4) Set test parameters (speed, load, cycle count) in the control system.
(5) Start the machine; wheels roll continuously and periodically pass over bumps.
(6) Monitor the test for abnormal vibration, noise, or alarms.
(7) Upon reaching the preset cycle count or failure, stop the test.
(8) Inspect the bicycle frame, suspension, and wheel assemblies; record results.
Test Procedures
(1) Select test conditions based on applicable standards: load, speed, and cycle count.
(2) Mount the bicycle on the test frame, adjust wheelbase, and secure wheels.
(3) Install the appropriate loading weights and check safety devices.
(4) Input parameters in the PLC control system and start the test.
(5) The bicycle runs over the bumps, generating dynamic fatigue impacts.
(6) Record operating status and any anomalies during testing.
(7) Stop the test after the set cycles or upon failure.
(8) Inspect and document frame, suspension, and wheel assembly conditions for evaluation.
Maintenance Information
(1) Regularly inspect drum, bump assembly, and loading weights for wear.
(2) Keep the frame and moving parts clean and lubricated.
(3) Check PLC system and sensors periodically for proper function.
(4) Ensure fan and cooling systems are operational for long-duration tests.
(5) Verify all safety interlocks before each test.
FAQ
1. What is this tester?
A dynamic durability testing machine that evaluates complete bicycle performance under simulated riding loads and road impacts.
2. What is it used for?
To assess the fatigue resistance, assembly reliability, and structural strength of bicycles under long-term dynamic conditions.
3. How does it work?
Weights are applied to the wheels while the drum rotates at a set speed. Wheels pass over bumps to generate cyclic vertical loads. PLC control monitors cycles and stops automatically if failure occurs or the set number of cycles is reached.
4. Why is this tester important?
It ensures bicycle safety and durability, supports R&D validation, and verifies compliance with international and domestic standards.
5. What industries is it suitable for?
Bicycle manufacturers, R&D laboratories, quality control labs, and third-party testing/ certification organizations.
