Abstract
The present invention discloses a method for the rapid assessment of the service life of a hub bearing under multiaxial random road loading, comprising the following steps: acquiring a measured load spectrum of a wheel center of an automobile, and converting the wheel center load into an axial load and a radial load borne by a hub unit; performing load level division on the axial load and radial load borne by the hub unit, and performing joint distribution counting; according to the deformation coordination relationship between a roller and a raceway of the bearing, establishing a bearing contact model under a joint load, and according to the bearing contact model and the result of joint distribution counting, calculating the actual contact load of the bearing under different loads; and calculating the equivalent dynamic load and the life of the bearing through the actual contact load of the bearing to obtain the total equivalent damage of the bearing. The present invention can accurately and effectively obtain the service life of the hub bearing to provide a reference basis for the design and type-selection, and life prediction of the hub bearing.
