Bicycle Frame Horizontal & Vertical Durability Tester
The Bicycle Frame Horizontal & Vertical Durability Tester is designed to simulate the horizontal and vertical load conditions experienced by bicycles during actual riding. You can use this tester to perform fatigue and durability testing on bicycle frames, evaluating long-term fatigue resistance and structural reliability. The device applies cyclic loads via servo cylinders, with force sensors operating in closed-loop control to ensure high loading accuracy. You can preset the number of cycles, and the system supports automatic direction reversal and automatic stop.

Test Principle
The tester applies cyclic horizontal and vertical loads to the bicycle frame via servo cylinders. Force sensors operate in closed-loop control to maintain the set force. When the target force is reached, the system automatically reverses direction for the return stroke. Horizontal loading simulates side-to-side forces during riding, while vertical loading simulates rider weight and ground impact. This ensures high-precision fatigue and durability testing.
Operation Instructions
(1) Securely mount the bicycle frame in the test area.
(2) Turn on the main power; the system performs self-checks and displays the PLC touchscreen interface.
(3) Set test parameters: loading force, frequency, number of cycles, etc.
(4) Start the test; the device automatically executes horizontal and vertical fatigue cycles.
(5) After the test, the system automatically stops, data are recorded, and the test area is cleared.
(6) Periodically inspect sensors, fixtures, and cables, and maintain lubrication and cleanliness.
Test Procedures
(1) Select the test mode (horizontal durability or vertical durability).
(2) Choose fixtures appropriate for the frame wheelbase and mount the frame.
(3) Set the test force, frequency, and number of cycles.
(4) Start the test and monitor force and cycle count in real time.
(5) At the end of the test, the PLC automatically stops the machine and saves data.
(6) Inspect the frame for structural changes, wear, or deformation.
Maintenance Information
(1) Regularly check the integrity of the servo cylinders and force sensors.
(2) Maintain cleanliness of fixtures and test area.
(3) Lubricate moving parts periodically.
(4) Verify calibration of sensors and PLC system for accurate results.
