In operation, the connecting rod is subjected to both gas pressure and inertia loads, and therefore, it must be adequately strong and rigid and light in weight as well. In order to improve the sufficient fatigue strength, stiffness, well static and dynamic mechanical properties under a variety of alternating load condition, it became a key question that how to even more base design decisions on virtual prototypes and to optimize the whole mechanism development process. In the paper, firstly, we propose a physical model of connecting rod mechanism. Secondly finite element analysis and simulation of the model is taken. Then its flexible multi-body dynamic model is established by ADAMS/View. The method provides the theoretical evidence for connecting rod structure improvement and optimum design.","PeriodicalId":415118,"journal":{"name":"2010 International Conference on Mechanical and Electrical Technology","volume":"22 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":"127813555","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 fitness of PSO is set up based on analysis on the modal assurance criterion(MAC) for measurement point optimization. After setting up finite element model and proceeding modal analysis of gearbox, particle swarm optimization with dynamic accelerating constants (CPSO) is applied to optimize and dertermin the numbers and locations of sensors for gearbox. In optimal process the fitness function is taken as evaluation object. The method discribed in this paper is proved to be feasible by an example of gearbox fault diagnosis.

A traditional proportional-integral-derivative (PID) controller was first designed and developed to demonstrate the basic and stable response of the manipulator in performing trajectory tracking tasks. Later, the AFC section was incorporated into the control scheme in cascade form by adding it in series with the PID controller (PID+AFC), its primary aim of which is to improve the overall system dynamic performance particularly when the manipulator is subjected to different loading conditions. Results clearly illustrate the robustness and effectiveness of the proposed AFC-based scheme in rejecting the disturbances compared to the traditional PID controller.","PeriodicalId":415118,"journal":{"name":"2010 International Conference on Mechanical and Electrical Technology","volume":"22 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":"133819437","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 other top and bottom walls are considered thermally insulated. The enclosure in the present work is based on the geometry of Tofiqul Islam et al. [9], (2007) which is considered inclined with inclination angles ranging from 0° to 30° and filled with water as a working fluid where its Prandtl number is taken as 6. All the numerical calculations are performed at the external Rayleigh numbers 103 and 106 while the internal Rayleigh numbers ranging from 105 to 108.
