The cylinder sample employed is a standard double rod cylinder with a cube body, and the ultrasonic oscillator has a measured resonant frequency of 31.65 kHz. The two components are connected through screw thread for effective oscillations. A measurement system is established and the influence of ultrasonic oscillator's frequency, exciting voltage and relative exciting position on static friction characteristics is explored. The experiment results prove the existence of cylinder friction reduction with ultrasonic oscillations compared to that of non-oscillation. And the static friction can be reduced to 60% of non-oscillation friction around the oscillator's resonant frequency.","PeriodicalId":241423,"journal":{"name":"Proceedings of 2011 International Conference on Fluid Power and Mechatronics","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130492678","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}

Hydraulic actuators have been chosen to drive active joints in order to meet the performance requirements of the robot for torque, compactness, velocity, impact resistance and control bandwidth. The main research work aims at the design of robot structure, descriptions of geometry relationships, parameters selection and implementation of jumping movement. The evaluations and analyses of the robot have finished based on the simulation results using AMESim software.

A terminal sliding mode controller can drive the close-loop system to stable in finite time. In this paper, based on a rigorous mathematical analysis and Lyapunov stability theory, a terminal fuzzy sliding mode controller is designed that the controlled system state can be driven to zero state. The terminal fuzzy sliding mode controller combines the terminal sliding mode control with the fuzzy sliding mode control. For the Duffing-Holmes system, the simulation results demonstrate that the proposed controller is able to drive the system to zero state and eliminate the chattering within a finite time.","PeriodicalId":241423,"journal":{"name":"Proceedings of 2011 International Conference on Fluid Power and Mechatronics","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115342923","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}

A tubular linear machine with double-layered Halbach arrays is proposed in this paper to enhance the magnetic flux density, and thus the force output. The magnetic field of the machine is formulated analytically with vector potential and Bessel's functions. The analytical model is validated with numerical results. Furthermore, the effect of back iron on the design is also analyzed. The study shows that the employment of double-layered Halbach arrays and back iron does help to improve the performance of the linear machines.

The table is mainly composed by a pneumatic actuator, the high-performance pneumatic servo valve and pipelines. The pneumatic actuator utilizes a pneumatic cylinder with air bearings. This servo valve, with high dynamics up to 300Hz, is connected with the pneumatic actuator by pipelines. The whole system is pneumatically driven, it has advantages like low heat generation and non-magnetic, which are suitable for precise positioning. A linear model considering the dynamics of pipelines and the servo valve is designed to simulate the system. Compared with experimental results, it is found that with 7th order linear control model, the discrepancy between experimental and simulation results became much smaller than the 3rd order model was used. However, a low dimensional model is necessary for practical use. Since there are two poles which are much further from imaginary axis compared with other five poles in the pole loci of the 7th order model, the model's order can be reduced into 5th. By comparing simulation with experimental results, we found that the 5th order model can also match with the real system well. Based on this result, a 5th order feed forward has been designed. When a curve which can derivate by five times is inputted, the experimental results show that the maximum trajectory has been minimized by 20μm.","PeriodicalId":241423,"journal":{"name":"Proceedings of 2011 International Conference on Fluid Power and Mechatronics","volume":"19 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123691451","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}
