Magneto rheological dampers, which are semi-active suspension equipment that use magneto rheological fluids to produce controllable force, can be used as smart actuators to reduce the vibrations of mechanical systems. An analytical study is performed in this article to examine the effectiveness of this type of actuator in suppressing the vibrations of a tracked vehicle suspension system. Based on the fluid mechanics theory, an amendment dynamic model of magneto rheological damper is derived. Considering the suspension characteristic and uncertainty of a magneto rheological damper, a variable universe fuzzy controller is designed to achieve a control of active variable damping. The results proved that the derived magneto rheological damper dynamic model is correct and indicated that the designed variable universe fuzzy controller could reduce the tracked vehicle vibration, which will further establish the basis of engineering application for a magneto rheological damper on semi-active suspension.","PeriodicalId":317730,"journal":{"name":"2011 IEEE International Conference on Mechatronics and Automation","volume":"137 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115035378","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}

Numerous approaches have been presented for path planning of mobile robots. One of the most efficient methods is Pulse Coupled Neural Network (PCNN). This paper presents a novel approach we call the Sparsed Potential PCNN method for real time path planning for mobile robots. In the proposed method a Potential Field approach is used to limit the propagation of the autowave only in the direction of the destination rather than propagating in all directions. This increases the efficiency of the PCNN algorithm. Furthermore a sparsing technique is applied to make the algorithm even more time efficient. The algorithm has proven to be a robust and time efficient path planning scheme. The Sparsed Potential-PCNN plans the shortest path in the shortest possible time. The algorithm is also capable of avoiding obstacles in its path. Simulation results in Player/Stage for Pioneer 3 AT mobile robot navigating among obstacles in an indoor environment are also presented to demonstrate the effectiveness of the proposed algorithm.","PeriodicalId":317730,"journal":{"name":"2011 IEEE International Conference on Mechatronics and Automation","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115352826","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}

The experiments were conducted using a testbed equipped with a displacement transducer, a torque sensor, etc., to get the information on sinkage, driving torque, and drawbar pull. It was found that within certain water content, the trafficability of wet sand is better than that of the dry sand. On the other hand, the behaviour of a wheel when running over mud is very different comparing to the case of sand, for which the shear force tends to be negligible because of the near-flow property of the mud. It was also demonstrated that the cohesion of the mud can't be ignored since the mud will attach to the wheel so that the shear force is offered by the internal friction angle of mud rather than the friction between wheel and soil. In the numerical work, DEM (discrete element method) was used to simulate the interaction between wheel and sand, and the agreement with the experiments was fairly good.","PeriodicalId":317730,"journal":{"name":"2011 IEEE International Conference on Mechatronics and Automation","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114277578","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}

In the present paper, a novel rotor-embedded-type MDOF spherical ultrasonic motor (SUSM) is proposed. The MDOF-SUSM consists of a spherical rotor and a stator vibrator with an all-in-one structure. The spherical rotor is embedded in the center of an almost annular stator vibrator with a spherical inner surface, and a motor shaft is mounted on the rotor. The stator vibrator with piezoceramic disks and plates adhered to the surfaces of the vibrator can excite five vibration modes, independently and simultaneously. The spherical rotor can rotate around three axes by combining two of the five vibration modes. The present paper describes the basic construction and the operating principle of the rotor-embedded-type MDOF-SUSM, modal analysis results for the stator vibrator, and some experimental results based on a trial manufacture. The proposed MDOF-SUSM confirmed the operating principle of the design, and it has a simple structure and is compact and lightweight, a large torque-to-weight ratio is expected to be realized.","PeriodicalId":317730,"journal":{"name":"2011 IEEE International Conference on Mechatronics and Automation","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114102704","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}
