J. Cent. South Univ. (2020) 27: 490-499 DOI: https://doi.org/10.1007/s11771-020-4311-4 Multi-component opportunistic maintenance optimization for wind turbines with consideration of seasonal factor.... To utilize the maintenance opportunities for the components among the wind turbines, opportunistic maintenance approach is adopted. Meanwhile, the influence of seasonal factor on the component’s......
:1672-7207(2015)01-0295-09 Structural damage identification based on factor analysis and sequential probability ratio test MIN Zhihua1, SUN Limin2, WANG Yin1 (1. College of Civil Engineering... damage identification based on factor analysis and sequential probability ratio test was proposed. The structural condition features, which were extracted from the monitoring data, were not only affected......
in continuum mechanics, damage factor is defined as [13] ...; (3) where D is the damage factor of material, Vp is the velocity of P-wave in actual material, and Vf is the velocity of P-wave......
damage subjected to cyclic loading, which is a very important factor that should be considered in the engineering design or service, has different mechanism with that static loading. For this reason... J. Cent. South Univ.
