Firstly, the functional requirements of knob operated shift strategy were analyzed, a simulation system based on finite-state machine was established in Simulink/Stateflow , the input and output signals, and the parameters of the model were scaled. Secondly, C code were automatic generated by use of EC toolbox, test cases were compiled with Excel , model in loop (MIL) and software in loop (SIL) auto test tool were used and the model was tested and modified. Test results indicate that, under different conditions, the dynamic response of knob operated shift function meet the design requirements.","PeriodicalId":209243,"journal":{"name":"2019 International Conference on Advanced Manufacturing, Computation and Optimization (AMCO 2019)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115615798","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}

But manufacture/Installation error and tooth profile error greatly affect the error of cycloid steel ball transmission. The quantitative study of transmission accuracy affected by manufacture/ processing error can control the very error in purpose and with special emphasis, and assure the transmission to reach expected accuracy. It is also very important to study the tooth profile accuracy of cycloid plate, which is the key transmission part of cycloid steel planetary transmission, and the factors affecting the accuracy as well. This paper analyzes the relationship between the transmission mechanism’s structural parameters and cycloid tooth profile error.","PeriodicalId":209243,"journal":{"name":"2019 International Conference on Advanced Manufacturing, Computation and Optimization (AMCO 2019)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121511455","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}

Firstly, this paper introduces a design of parallel precision piston pump that drived by AC servo motor. This paper work out the correlation between flow and law of motion. At the same time, paper conducts the positive relationship between non-uniformity of displacement and control accuracy of the system, the inversely proportional relationship between non-uniformity of displacement and length of stroke. Paper provides theor etical foundation for constant flow output and the design of control system.","PeriodicalId":209243,"journal":{"name":"2019 International Conference on Advanced Manufacturing, Computation and Optimization (AMCO 2019)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127997171","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}
