This system can collect compressive force, compressive force of test platform wall and deformation of herbage materials and so on during compression process, and can process all data in real time. Taking alfalfa as experimental materiel, stress relation experiments are conducted on baling test platform in five different sections, which has posted that stress relaxation curves of compressed alfalfa piece have same character in different sections, i.e. the stress sharply reduce in the initial period and change slowly in the later period. Meanwhile, the initial stress is more and the stress after relaxing is more. The viewpoint of choosing compression frequency by stress relaxation ratio is educed, and it suggests that compression frequency of baler shouldn't be too high. Compression frequency can be chosen lower if initial density is bigger. Therefore the aims of reducing energy consumption, ensuring productivity and stable product quality can be achieved.","PeriodicalId":6349,"journal":{"name":"2010 International Conference on Mechanic Automation and Control Engineering","volume":"1 1","pages":"5892-5895"},"PeriodicalIF":0.0,"publicationDate":"2010-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72553651","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 performance under different pressures of the press was investigated. The press system mainly composed five parts: support frame, round press plates, cylindrical sieve vessel, collection bucket and hydraulic power system. When the pressure increased from 10 MPa to 35 MPa, the residues water content decreased from 87.6% to 81.3% and the fresh water hyacinth volume reductions rate rose from 35% to 77%, and the average WHPJ production was 0.32 kg per kg fresh water hyacinth. The physicochemical characteristics of WHPJ such as pH, EC, SS, COD, TN and TP all varied with the pressure increasing. When the pressure increased from 10 MPa to 20 MPa the content growth rate of per parameter was small, but the pressure continue to increase the content of all parameters are rapidly rising, pH and EC excepted, the WHPJ characteristics can be adjusted by different pressures. According to the experimental results, it may be inferred that this press was shown to be suitable for water hyacinth dewatering of having evident waste reduction and efficient of juice production.","PeriodicalId":6349,"journal":{"name":"2010 International Conference on Mechanic Automation and Control Engineering","volume":"19 1","pages":"2614-2617"},"PeriodicalIF":0.0,"publicationDate":"2010-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75039665","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 research shows that while being subjected to dynamic loading, such as traffic load, the soil's stiffness softening is occurring more or less when the cycle number is increasing. There are three experimental types of saturated soft clay under dynamic loading with different cycle stress level, such as stable type, destructive type and critical type. The critical type of stress is called critical dynamic stress. There is little difference on numerical value between two critical dynamic stresses which identified by strain and pore pressure respectively. Meanwhile, it shows that dynamic shear modulus falls as dynamic strain increases, and the relationship between dynamic shear modulus and cycle number is influenced by cycle number. So when we design the foundation, dynamic shear modulus should be decided according to dynamic strain and cyclic number. Damping ratio increases as long as dynamic strain increases. The confining pressure has little influence on the relationship between dynamic shear modulus and cycle number.","PeriodicalId":6349,"journal":{"name":"2010 International Conference on Mechanic Automation and Control Engineering","volume":"41 1","pages":"4498-4501"},"PeriodicalIF":0.0,"publicationDate":"2010-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76497166","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 key part II of the purification, because of the harmful impurities cobalt ion concentration can not be on-line measured, and the testing results is two hours later before the production situation, it is mainly through the production of excessive addition of antimony salts and zinc to remove cobalt ions. Under the premise of deeply analysis of the process II of product and purification technique and the relevant factors, a control method was brought forward in this article, which adopts the same dimension grey prediction method to forecast cobalt ion concentration, and then uses a neural network technique to compensate the error of grey forecast. In the end of the article, two simulated experiments of the neural network grey model (NN-GM) and the least square support vector machine (LS-SVM) were compared. The results of the simulation and production practice has proved that the NN-GM model can be so better to predict the cobalt ion concentration values, that played guiding role for the operation process in optimize the antimony salt and zinc addition.","PeriodicalId":6349,"journal":{"name":"2010 International Conference on Mechanic Automation and Control Engineering","volume":"85 1","pages":"3802-3806"},"PeriodicalIF":0.0,"publicationDate":"2010-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77498756","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}
