Based on the experimental data on the temperature of the outer surface of the metal wall of the shell, using the approximate analytical solution of the heat conduction problem for a two-layer turbine wall (thermal insulation - turbine body), the heat transfer coefficients on the inner surface of the wall (the vapor side) were found by solving the inverse heat conduction problem. The heat transfer coefficients obtained this way were used to determine the temperature condition of the turbine HPC by the wall thickness and thermal insulation in various sections of the body. Using the results of calculations of the turbine HPC body temperature condition by the finite element method, the temperature stresses in the longitudinal section of the body were found. Their analysis allows concluding that the magnitude of the temperature stresses does not exceed the tensile strength limit for a given material. In this case, the stresses arising from the vapor pressure forces and from the non-uniformity of the temperature distribution in the circumferential direction were not taken into account.","PeriodicalId":177690,"journal":{"name":"2018 International Multi-Conference on Industrial Engineering and Modern Technologies (FarEastCon)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122049694","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}

This article suggests a prediction algorithm based on creating approximation of prior series sample as a linear combination of an existing set of samples. Here, prediction is an obtained linear combination of the continuations of approximating samples. The problem of finding the coefficients of the linear combinations is written as an A. N. Tikhonov's extremum problem of least-squares with a regularizer, which allows creating a system of equations for evaluating the unknown parameters. Solving the system of equations is carried out using the singular spectrum analysis (SSA). Regularity helps to increase the solving quality in noisy conditions. After isolating the singular components of the system of equations matrix, the solution can be obtained in analytical form. The parameters governing the quality of the solution are the regularization coefficients and the set of components of the singular decomposition. The prediction efficiency index is estimated based on the discrepancies between the prediction and actual values of the series for the given depth of the prediction. The prediction model search is done by choosing the best model on the set of values of the regularization parameter with different sets of eigenvectors that determine the solution space. The proposed method was tested on different time series. The examples of prediction of the energy market indicators prove its effectiveness.","PeriodicalId":177690,"journal":{"name":"2018 International Multi-Conference on Industrial Engineering and Modern Technologies (FarEastCon)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114552923","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}

During the identification, it becomes important to create a model that is the correct reflection of the structure and parameters of the object. The suggested method, based on continued fractions and Z-transform that allows avoiding inaccuracies that reduce the control quality. In order to define the direct indicators of the control quality it is necessary to calculate the transfer function of the system, which is not possible without computer technology or plotting each set of values of the controller parameters. This becomes meaningless when a stochastic effect is applied to the input of the system, since the control time in this case will depend not only on the regulator settings, but also on the realization of the random process fed to the system input. In this paper, we propose an approach that determines the time for regulating the system using a formula that depends on the coefficients of the transition characteristic. This will avoid multiple recalculation of its values, and will make it possible to use known methods for adjusting regulators for systems with stochastic input effects.","PeriodicalId":177690,"journal":{"name":"2018 International Multi-Conference on Industrial Engineering and Modern Technologies (FarEastCon)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124142292","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 electromagnetic, electromechanical and thermal processes are poorly researched in such installations, and the design development, and moreover, construction and heating regime optimization of such installations require deep understanding of them. This paper is concerned with completed researches of electromechanical and energetic characteristics of induction heating system workpieces made from nonmagnetic metals with low specific electrical resistance (aluminium, copper, bronze) by cross magnetic field of rotated permanent magnets, and also the effect of magnetic field concentrators on the heating of non-cylindrical billets is shown.
