Spring hardware products are prone to resonance with external excitation at certain frequencies, which can lead to a sharp increase in amplitude and may cause structural damage or performance degradation.
Aluminum processing requires the use of high-purity aluminum alloys with uniform microstructure to reduce deformation and internal stress during processing.
In terms of structural design, the geometry and force distribution of the fork directly affect the degree of stress concentration under dynamic loads.
In the daily lives of wheelchair users, every stop, every ramp parking maneuver, and every transition between getting in and out of the wheelchair relies on a seemingly simple yet crucial device—wheelchair brakes.
The complex three-dimensional curved surfaces, variable cross-section transitions, and local reinforcing ribs of aluminum wheelchair forks pose extremely high challenges to forming precision.
As a core load-bearing and moving component, the wheelchair folding backrest must withstand tens of thousands, even hundreds of thousands, of opening and closing cycles without breakage, deformation, or functional failure, while maintaining a lightweight
