Introduction to Bicycle Disc Brake Mount Dynamic Fatigue Testing Machine

1. Core Definitions and Uses

The Bicycle Disc Brake Mount Dynamic Fatigue Tester is a specialized testing device designed to simulate the stress state of a bicycle frame's rear or front fork under long-term, high-frequency braking conditions. It applies alternating loads to forcibly accelerate the metal fatigue process of the disc brake mount (the metal base that mounts the brake caliper), verifying its structural strength, welding quality, and material durability. It serves as a crucial quality control barrier to ensure riding safety and prevent fork breakage accidents.

2. Working principle ("brute force" simulation)

This device abandons traditional whole-vehicle road testing and adopts a "fixed-point explosion" type of mechanical simulation logic:

3. Core performance indicators (technical strengths)

According to ISO 4210, EN 14766 and GB 3565 standards, the parameters of mainstream models are as follows:

4. Testing Standards and Criteria

The equipment strictly adheres to international safety standards, and test results directly determine whether a product can be marketed:

ISO 4210-5 (Frame and Fork): Requires the frame to withstand a specified load (e.g., 1000N) for 100,000 cycles without visible cracks, and the deformation must be within permissible limits.

EN 14766 (Mountain Bikes): Provides specific lateral and vertical fatigue testing requirements for disc brake mounts.

Acceptance Criteria: After testing, the weld seam and base material at the base of the disc brake mount are inspected using magnetic particle testing or dye penetrant testing. The absence of any cracks exceeding 1.5mm in length constitutes acceptance.
