Abstract
In order to establish bearing fatigue life model considering the effect of load sequence, a new fatigue damage accumulation theory and material fatigue limit stress were introduced based on the Miner theory and improved L-P theory. Taking deep-groove bearing 6205 as an example, the effects of load type, mean load, load amplitude, load frequency and rolling speed on bearing life were analyzed by combining bearing quasi dynamic calculation software. The results show that, comparing to equivalent load method, the modified life model can fully reflect the effects of the above mentioned five factors. The effect of load sequence is also considered in this modified life model.
