Advanced Testing Methodology & Mechanics

The system is meticulously engineered to replicate severe real-world crash conditions through a precise, controlled free-fall mechanism:

• Standardized Loading Profile: The machine features a high-stability 70kg deadweight mass rigidly secured to the seat post. The system ensures the center of gravity (CoG) is positioned precisely 75mm above the top-tube line along the seat post axis, satisfying the exact geometric requirements of international test protocols.

• Pivoting Free-Fall Simulation: The entire frame-and-fork assembly is mounted so that it can pivot freely in a vertical plane, centered on the rear axle attachment point. The front fork rests initially on a heavy-duty, flat steel anvil.

• Dynamic Impact Execution: To initiate the test, the assembly is rotated until the 70kg center of gravity is positioned vertically above the rear hub axis. Upon release, the assembly undergoes an unhindered free fall, allowing gravity to accelerate the front fork until it strikes the solid steel anvil. The rig is designed for consecutive, highly repeatable impact cycles to measure structural deformation and cumulative material fatigue.

Key Engineering Features

• Rugged Heavy-Duty Construction: Built with an ultra-rigid steel frame and a reinforced base plate to absorb high-energy impacts without system deflection, ensuring accurate and uncorrupted test data.

• Precision Anvil Design: Features a hardened steel anvil with superior flatness and wear resistance, maintaining standardized surface conditions over thousands of cycles.

• Ergonomic Control Interface: Equipped with user-friendly controls for safe clamping, precise angle positioning, and reliable release mechanisms, mitigating operator error and optimizing workflow efficiency.

• Uncompromised Laboratory Safety: Integrates robust mechanical safety locks and physical enclosures to protect laboratory technicians during high-mass dropping sequences.

Broad Industrial Applications

This bike falling mass impact test rig is universally applicable across the micromobility sector. It delivers unparalleled verification data for:

• Mountain bikes (MTB), road racing bikes, city/trekking bikes, and high-performance e-bikes.

• Advanced material evaluations, including carbon fiber, aluminum alloy, and titanium alloy frames.
