Starting with a relatively simple thermodynamic cycle without heat leakage, the best configuration for a hot engine and a refrigerator cycle is studied under the condition of a relatively simple linear and phenomenological heat transfer laws. On this basis, a modified Lagrangian is established, and the given cycle period and the maximum output work [1] are taken as the constraints. The variation law of high temperature heat source and work medium temperature can be obtained by solving the EULER–Lagrange equation, optimum configuration of instantaneous heat engine. The mathematical model is established by variational method and numerical solution method, and the numerical solution is obtained by iterative method with Matlab software.","PeriodicalId":6873,"journal":{"name":"2021 3rd International Conference on Artificial Intelligence and Advanced Manufacture","volume":"282 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82824912","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}

For the purpose of preparing advanced materials of high temperature resistant polyurethane adhesives, 1,2-bihydroxymethyl carborane was synthesized by the reaction of o-carborane with n-butyllithium and paraformaldehyde, which was employed to prepare the hydroxy-terminated carborane polyester diol with sebacylchloride by the condensation reaction. The structure of the monomer and the polymer was characterized by infrared spectroscopy and 1H NMR. Bi-component polyurethane adhesives were prepared by using the hydroxy-terminated carborane polyester diol as component A and polyisocyanate curing agent (Bayer N3300 and PAPI) as component B, and their molecular structure, shear strength, thermal properties and high-temperature structural evolution were characterized. The results showed that shear strength of the adhesive was higher than 10 MPa at room temperature and low temperature, and higher than 1 MPa after treatment at 600℃ for 1 hour, and the char yield was higher than 40% in nitrogen atmosphere and 60% in air atmosphere at 800℃.

Frequency characteristic is one of the most important characteristics of truss structure. Generally, the finite element method can well predict the modal information of truss structure, which has little calculation and convenient modeling. However, considering the optimization problem, a few parameters can produce millions or even billions of combinations. It will take unbearable time to use the finite element method alone. Therefore, this paper introduces BP neural network for faster frequency prediction and optimization. Firstly, a four node 4-bars truss structure is established, and its characteristics are characterized as the combinations of five parameters. Secondly, the frequency characteristics of 3125 truss structures with different parameter combinations are calculated by finite element method. Thirdly, BP neural network is trained to obtain the corresponding relationship between the parameter combination and frequency characteristics of truss structure. Finally, the trained BP neural network is used to optimize the truss parameters. This method can obtain the parameter combination with the highest frequency under limited conditions, which indicates that it is an effective method.","PeriodicalId":6873,"journal":{"name":"2021 3rd International Conference on Artificial Intelligence and Advanced Manufacture","volume":"57 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85755187","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}
