Cylindrical roller bearing is often used in aeroengine main-shaft system because of its excellent capability working at high speed and heavily loaded condition. With the promotion of aeroengine performance both the higher speed and higher temperature etc., the dynamic working performance of the bearing attract more and more researcher's attention. This paper attempt to achieve a more accuracy simulation...
Danger Model Immune Algorithm (DMIA) is an algorithm based on the danger theory of biological immune system, and it has a good performance in optimization. DMIA is proposed to initialize the weights and biases of wavelet neural network (WNN), the ergodic weights and biases are used for further net-training. The fault diagnosis for marine diesel engine is conducted by using the well-trained wavelet...
ETO product was mostly complicated product, and it was designed on the basis of especial customer requirement. The framework of ETO product configuration design and multidisciplinary optimization was put forward, through analyzing key problem of ETO configuration design; based on design knowledge and tabular layouts of article characteristics, designer could fleetly configure ETO product in accord...
Based on the artificial immune system, a new clonal selection algorithm is proposed to perform global optimization. The concept of classified mutation is defined and the dynamic adjustment methods of some evolution parameters are introduced. The proposed algorithm is applied to several benchmark problems, and its performance is compared with other approaches in the literature. The results indicate...
