Objective
Testing bicycle wheels lifetime 

 

Problematic
The endurance bench must be modular, this way, each modulus must provide a particular simulation function. 

 

Solution and result

The endurance test bench designed and conceived by our engineering team is self-supporting and ergonomic. The wheel is placed on an arm, which is itself mounted on a vertical-axis mobile cart. A vertical force is thus applied to the wheel.  

The system is conceived in order to test different wheel dimensions and sizes, with a minimum of handling operations. The user can set the wheel inclination thanks to a stem. The angle can vary of +/- 30° from the vertical axis. 

The wheel rolls on a motorized drum, simulating the bike movement. An accelerometer measures the wheel accelerations, and a force sensor (which simulates the weight of a cyclist) evaluates the supporting force. This drum can also be replaced by a conveyor belt. 

A specific software carries out test programmes which combine all the intended functions. Data such as motion speed and the covered distance are recorded in an automatic test report. 

The endurance test bench for bicycle wheels is usually located in test labs, in order to test the fatigue resistance and lifetime of wheels before their production launch. 

The bench being modular, LF Technologies can easily consider adding new functions, such as simulating bumps, break, etc.
