While the boom is being lowered, the constantly changing geometry results in a steadily increasing load pressure acting on the luffing cylinder. This requests the load control valve to have perfect performance including opening characteristic, jiggle characteristic, load pressure over-compensation characteristic and dynamic response characteristic. However the luffing hydraulic system with traditional load control valve has the problems of high system pressure, large impact and easily vibrated. This paper introduces the working principle of a new piloted follow-up load control valve first, and then develops a simulation model, which is validated by a series of experiments conducted on the automobile crane. Based on theory research and simulation, the working mechanism is analyzed and it demonstrates that the piloted follow-up load control valve have a opening characteristic independent of load, good jiggle characteristic under low control pressure, load pressure over-compensation, and smooth dynamic response without overshoot, which are all essential in automobile crane luffing system.","PeriodicalId":169447,"journal":{"name":"2013 Fifth International Conference on Measuring Technology and Mechatronics Automation","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123706947","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 this paper we present an algorithm based on an improved Structural Holes method to identify the key nodes of a complex network. Since our approach does not need to consider the global structure of a network but only consider the number of one node's neighbors and it's next nearest neighbors, the nodes importance can be calculated with local information of a complex network. Experimental results of ARPA net show that our method is better than some important ranking measures such as between ness, degree or closeness. It is very useful for evaluating the key nodes in large scale and complicated networks, in which evaluation of nodes importance is almost impossible to calculate with global information.","PeriodicalId":169447,"journal":{"name":"2013 Fifth International Conference on Measuring Technology and Mechatronics Automation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124022298","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 novel guidance goals are 1) to minimize the final miss distance between target and interceptor, 2) to ensure that the missile approaches target at certain strike angles to improve lethality, 3) to require the vehicle to use minimum energy to hit the target, and 4) to achieve high robustness vis-a-vis severe parameter dispersion effects resulting from aerodynamic coefficient errors. Numerical tests show that this proposed guidance scheme exhibits high performance and high robustness against the stationary target. Compared to the optimal trajectory shaping law through simulation, the results demonstrate that this PCTSG algorithm performs more advanced, due to two factors: 1) the attack time from launch to hitting the target decreases, 2) the required acceleration command is almost linear and much less.","PeriodicalId":169447,"journal":{"name":"2013 Fifth International Conference on Measuring Technology and Mechatronics Automation","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129459281","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}
