An integrated health condition detection method for rolling bearings using …

Rolling bearings usually works in the condition with high speed, high temperature and high pressure, so their faults need to be detected and judged in time. This paper presents a new multi-scale entropy measurement algorithm called time-shift multi-scale amplitude-aware permutation entropy (TSMAAPE), coining time-shift coarse-grained method and multi-scale amplitude …

BEARING CAPACITY FOR SHALLOW FOUNDATIONS

20/6/2016· BEARING CAPACITY FOR SHALLOW FOUNDATIONS. The bearing capacity of a shallow foundation can be defined as the maximum value of the load applied, for which no point of the subsoil reaches failure point (Frolich method) or else for which failure extends to a considerable volume of soil (Prandtl method and successive).

Rolling bearing fault feature extraction using non-convex periodic group sparse method …

The detection and evaluation of early faults is currently an important issue in the condition assessment of machinery and has been a challenging problem. In this paper, a novel index and a periodic enhancement group sparse (PEGS) model are sequentially proposed for early fault feature extraction of rolling bearings. Firstly, an index is defined based on the energy operator …
