To solve the problem of matching slabs and coils against orders in the process of hot rolling production in steel industry, we introduce matrices in which the element indicates difference between slab material and steel required in order, and also matrices in which the element indicates difference between coil and steel required in order. A multi-objective 0–1 programming model is established. And...
In the present work the model of an electromagnetic device that corresponds to an electric machine with stator core fault is presented. The acquisition process of the mathematical model and the equivalent Bond Graph model is based on its Magnetic Equivalent Circuit derived from the idealized physical system. From the experimental results, the non-linear characteristic of the magnetic material is reproduced...
This paper presents the study of a multi-phase induction system for metal disc heating. It proposes a complete electrical and thermal modelling of the whole system in PSim software, with a reduced simulation time. An optimisation procedure allows us to calculate the optimal parameters for calibrating the system in order to obtain a uniform heating of the work piece. This was possible from the knowledge...
During the process of die less drawing, the relationship between shape of metamorphic zone and technical parameter is very complicate. It is difficult to determine the mathematical model of die less drawing shaping zone because the technical parameters is very coupling. After analyzed the data of experiment zone deeply, the article realized predictive functional control algorithm based on the characteristic...
In this work we present results of numerical modeling based on Pocklington integral equation of flat superlenses composed of helixes and linear half-wave pieces as well as of helical coils facing in different direction. The resolution of lenses was determined. Experimental results, which confirm the mathematical model to be appropriate, are presented.
In this article, theoretical and experimental study are presented for positive and inverse characteristics of magnetically controlled shape memory alloy (MSMA). The experiment model of self-sensing actuator (SSA) based on MSMA is designed. And working principle of the prototype & a mathematical model are shown. The experiment model of SSA based on MSMA uses dual-coil structure with sensor coil...
Static thermal analysis of a coil has been presented in this paper. The system for temperature measurement has been designed and described. The calculation results obtained by using finite element method analysis have been verified experimentally.
In order to study the distribution of temperature field inside the induction coil drive, according to the single stage model of synchronous induction coil launcher, based on the vector magnetism place and the scalar quantity electric potential, the mathematical model of temperature field of conductor area has been established. Adopt the ANSYS finite element software, we have researched the temperature...
In order to realization electronic parts product appearance quality detection control, one kind of processor based on the intelligent knowledge automatic extraction and system intelligence modeling was presented. In the processor, wavelet-fuzzy technique and neural network technique are combined. Uses the fuzzy wavelet extraction image feature, and wavelet function is used as fuzzy membership function...
The real time monitoring and control of resistance spot welds is a problem of critical importance in automotive and many other manufacturing industries. However, till this date, there are no reliable, low-cost, non-destructive techniques for predicting the size and strength of the weld nuggets in real time. This paper investigates the usage of voltage, current, and force data for the above tasks....
