A compact and efficient sound absorbing structure without porous material is designed as a combination of baffle-resonators and Helmholtz-resonators comprising a perforated membrane with sub-millimeter holes backed by an air space. Its performance is predicted by equivalent electric-acoustic circuit analysis. Numerical examples are given. In addition, several important influence factors are discussed affecting on the acoustic absorption performance. The numerical computation results show that absorption performance is feasible more improved by using double layers of micro-perforated membrane and air space structure.","PeriodicalId":145608,"journal":{"name":"2010 IEEE International Conference on Mechatronics and Automation","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133365301","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}

By applying modified D-H method, a kinematical coordinate system of the pose and position control mechanism is set up and the forward and inverse kinematics models are also built up. After the design of control models and the simulation analysis of them, a simulation curve of the motion laws in one gait circle is achieved. The result of simulation shows that this mechanism can realize the control over four-degree motions of human pelvis and this research supplies theoretical basis for the design of control system and the realization of motion control in walking aid robot.","PeriodicalId":145608,"journal":{"name":"2010 IEEE International Conference on Mechatronics and Automation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133372343","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}

Both network-induced delay and data packet dropout are taken into consideration, and data packet dropout is regard as a kind of special delay. The synthetical delay is a interval time-varying delay, and possesses fast time-varying characteristic, namely, the derivative of delay is more than 1 and is difficult to determine the upper bound. Based on state feedback control strategy and the Lyapunov-Krasovakii approach, the delay-dependent robust guaranteed cost fault-tolerant control sufficient condition against sensor failures is derived. Because the Lyapunov- Razumikhin approach is not used and the lower bound of delay is introduced, the results possess less conservativeness. Meanwhile, the design approach of the optimal controller are given. Finally, an example is used to illustrate the effectiveness and the feasibility of proposed approach.","PeriodicalId":145608,"journal":{"name":"2010 IEEE International Conference on Mechatronics and Automation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130323432","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}

However, productivity is always the bottleneck to implement downsizing in practical production. On the other hand, eco-efficiency is considered to be the key issue in enhancing the sustainability of the society. In manufacturing system, system capability versus environmental impact should be focused on as system eco-efficiency. The researchers developed a downsized modular manufacturing system named on-demand MEMS factory. A comparison with a conventional MEMS fabrication facility showed that such downsized manufacturing systems are rather eco-efficient. We explained that the small size contributes in reducing the environmental impact and the modularity is good for enhancing system flexibility. However, the production flexibility itself has not been quantified. In this report, we modify the evaluation index to quantify the system ability to meet various requirements in production. Through this effort the paper analyzes that the on-demand MEMS factory is far more eco-efficient when the requirements for the manufacturing system changes frequently.","PeriodicalId":145608,"journal":{"name":"2010 IEEE International Conference on Mechatronics and Automation","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115349256","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 genetic operators (crossover and mutation) are adjusted self-adaptively by fuzzy controller and good convergent character and global optimization are improved. Based on the PML-FDTD method, the fitness value is established by taking the sum of weighted performance index function of crosstalk and return loss, through which is optimized the crosstalk between T-shape microstrip line and adjacent line in the ground plane. Comparing the simulation results of the fitness function using different parameters, numerical results demonstrate that the crosstalk is decreased 8dB which is caused by T-shape microstrip line and adjacent line above the photonic band gap ground. Then the return loss and the signal distortion reduce effectively.","PeriodicalId":145608,"journal":{"name":"2010 IEEE International Conference on Mechatronics and Automation","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115763049","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}

Based on the terramechanics, shear force and bulldozing resistance acting on the wheel are investigated. And the quantitative relation among rim radius, drawbar pull, driving torque and steering resistance moment (SRM) are established, which confirms that the increasing rim radius can improve the tractive performance of the wheel, in contrast, it also decreases the steering performance of the wheel. To validate the models, a single-wheel test bed is employed to test the rolling and steering performance of two wheels.
