Research on Online Non-Contact Test Device and Test Method for Bearing Stiffness of Electric Spindle

To enable experimental research on the dynamic support stiffness of electric spindle bearings, the authors designed a magnetic non-contact excitation and test device that can test the support stiffness of electric spindle bearings under a rotating state. The device includes load excitation and displ...
