The testing platform for axial direction preload of automobile hub bearing
- The axial preload test platform for axial preload of automobile hub bearing get the resonant frequency and damping coefficient between the inner circle and outer circle of the hub bearing unit by using resonance method, according to the hertzian contact theory. It determines the pre-load of automobile hub bearing by calculating and analyzing of the software program.

The maximum mass of testing bearing：5kg
The range of excitation frequency: 200～3000Hz（resolution 1Hz）
Maximum amplitude：±5mm
Maximum excitation force：15kg
Test parameters: resonant frequency and damping coefficient
