The flexjoint is spherical and consists of laminated rubber and metal layers. It's necessary to study the effects of Poisson's ratio and compressibility of the rubber on the flexjoint. Meanwhile, the effect of the number of metal layers is also studied. The 2D axisymmetric nonlinear finite element analysis is carried out to simulate the static behavior of the flexjoint under vertical compression. The Mooney-Rivlin strain energy function is used to describe the constitutive relation of the rubber. The effects of Poisson's ratio of the rubber and the number of metal layers on the vertical compression stiffness and the maximum equivalent stress of the flexjoint are studied. The increase of the number of metal layers will improve the vertical compression stiffness and reduce the maximum equivalent stress. When Poisson's ratio of the rubber material increases from 0.49 to 0.49995, the vertical compression stiffness of the flexjoint increases by 14.7 times. The maximum equivalent stress decreases as the number of metal layers increases and, in this case, the reduction is 115Mpa.","PeriodicalId":124642,"journal":{"name":"2017 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":"442 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133649009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Contract to traditional algorithm, the lasted research showed intelligent algorithms have remarkable advantages in multiple-peak output power characteristics affected by partial shading. This article presents some popular intelligent algorithms such as particle swarm optimization(PSO), genetic algorithm(GA), ant colony optimization (ACO), etc. When PV systems are affected by partial shading, these GMPPT (global maximum power point tracking) algorithm is required to increase the energy harvesting capability of the system. By analyze and discuss the search efficiency and convergence property of several intelligent optimization methods mentioned above, multiple problem still exist and the GMPP can not usually be tracked exactly and quickly. Thus, this article point out it is great significance that several hybrid intelligent algorithms are put forward to compensate the deficiency of single algorithms, and modified the optimization is also required.","PeriodicalId":124642,"journal":{"name":"2017 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133112461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its vibration signal is not easy to be recognized in the raw signal owing to its low energy level at the early stage of the fault and strong background noise. An early developed and still widely used technique for such a signal detection is envelope analysis. Despite the fruitful modifications and improvements on this technique, its effectiveness and application is still limited by its parameter selection, which is generally understood as the optimization on the structure and the parameters of the filter that are hardly ever known a priori. To solve this problem, this paper focuses on the adaptive selection of the filter parameters, i.e. the center frequency and the band width. By analyzing the energy distribution in frequency domain of the vibration signal, the center frequency is automatically determined by identifying the frequency with the maximal energy; and then, by comparing the energy changes of two adjacent windows and merging these windows if the changes are small enough, the appropriate band width is selected according to the window with the concentrated energy. An experimental vibration signal collected from a bearing with an outer race defect is used to verify the effectiveness of the proposed filter. A comparison between the proposed method and the fast kurtogram is also completed. The results indicate that the proposed filter can quickly identify the resonance frequency band induced by the faulty bearing and then extract weak transient signal for accurate fault diagnosis.","PeriodicalId":124642,"journal":{"name":"2017 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128817832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
