STUDY ON WEAR OF TAPERED ROLLER BEARING UNDER DIFFERENT SERVICE CONDITIONS
Published 2025-01-01“…In order to clarify the influence of different working conditions on the wear of tapered roller bearings, the wear state of tapered roller bearings was carried out.A quasi-statics model of tapered roller bearings including roller balance equation and inner ring balance equation was established, and a wear depth calculation model suitable for wear analysis of tapered roller bearings was derived based on Archard wear theory.The wear distribution characteristics of bearing inner and outer raceways and roller elements under light load, medium load and heavy load conditions were comparative analyzed.The results show that the wear depths of the tapered roller and the inner/outer raceways on the contact line show bimodal distribution characteristics, and the wear distribution of the outer raceway is closely related to the positions of the rolling elements.For light load condition, the peak wear depth of bearing raceways and roller elements increases by 20% as bearing speed increases 25%, and for heavy load condition, the peak wear depth of bearing raceways and roller elements increases more than 17% as bearing load increases 16%.The comparison of bearing wear peaks under the three working conditions shows that the product of the equivalent load and the speed of the bearing is not the determining factor controlling bearing wear,and the load change has a significant impact on the bearing wear.…”

Study on Landscape Fractal of Different Vegetation Coverage in Hilly Area of South China— Taking Conghua District of Guangzhou City as an Example
Published 2021-01-01“…Based on the fractal theory,this paper calculates the area,fractal dimension and stability index of patches with different vegetation coverage in Conghua District,and analyzes the distribution and variation law of patch fractal characteristics in different elevation,slope and aspect.The results show that:①The vegetation condition in Conghua District is generally good,and the patch area with medium (>45%) and above vegetation coverage accounts for 86.7% of the total vegetation area.The farther it is from towns and highways,the more complex and irregular the patch shape is.② When the elevation is less than 90 m,the proportion of patch area with low,medium and low vegetation coverage is larger,and the shape of all kinds of patches is fragmented and complex.When the elevation is higher than 90 m,the fractal dimension of patches increases and the stability decreases with the increase of elevation.③The topographic slope in Conghua District is mainly below 25 degrees.The patches with low and middle vegetation coverage are mainly distributed in the area below 15 degrees,while those with high vegetation coverage are dominant in the area above 15 degrees.With the increase of slope,the fractal dimension and stability index of patches with the same vegetation coverage do not change significantly.④The vegetation condition of sunny slope is better than that of shady slope,but the patch structure of shady slope is more complex.…”
