The testing platform for axial direction pre-loading of automobile hub bearing get the resonant

The testing platform for axial direction pre-loading of TAUh3050 automobile hub bearing

    The testing platform for axial direction pre-loading 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.

 

 

Main technical parameters:Testing type: bearing unit of automobile hubThe maximum shape of testing bearing (Φ×H200×150 mmThe maximum mass of testing bearing 5kgThe range of excitation frequency 2003000Hzresolution 1HzMaximum amplitude ±5mmMaximum excitation force 15kgTest parameters: resonant frequency and damping coefficient
