In this part, the gearbox mass and efficiency are first calculated in order to build the optimization problem. Next, the specified objective functions and constraints are given. To facilitate calculations, the nomenclature used in the optimization problem are presented in Table 1. Table 1. The nom...
Liu et al. [15] used the VOF method and MRF model to perform numerical calculations on the flow characteristics of lubricating oil in the cavity of high-speed angular contact ball bearings. Zhang [16] established a CFD calculation model for tapered roller bearings and found that the oil ...
The N parameter tends to be a more sinusoidal wave than the initial geometry, as verified by the reduction in the value of WTHD, which implies a non-oversizing of the filters of the converter. The peak values are similar between the geometries. So, considering constant rotor speed, the ...
Table 2. The transfer task settings in the lab gearbox dataset. For the bearing dataset of CWRU, the inner race fault, rolling fault, and healthy conditions data are set as the shared class, and the labels are set as 0, 1, and 2 in turn. The outer race fault data is the non-sha...
