Method of calculation of temperatures of warming-up of constructions of cylindrical electro-acoustic transducer of the compensated type, pressurized by the metal-polymer layers
Main Article Content
Abstract
The technique for the calculation of cylindrical electro-acoustic transformers constructions warming-up temperature on the basis of Fourier heat-conducting differential equation decision are worked out. The technique considers features of transformers pressurizing by metal-polymer layers widespread method designer realization and can be applied to the constructions of compensated type transformers. The system of five endless on a height layers in which piezoceramics is in the middle, and layers of polymeric materials and metal there are on either side is taken as a calculation model. The heat-conducting equation decision by means of which it is possible to define temperatures in the different points of transformer layers is found. On the basis of the got correlations it was set , that in the transformer construction polymeric shells there is a considerable overfall of temperatures, which can lead to their destruction because of temperature mechanical tensions origin.
