Variant of method of symmetries in a task about the vibrations of circular plate with a decreasing thickness by law of concave parabola
Main Article Content
Abstract
The decision of task is got about the vibrations of circular plate with a decreasing thickness by law of concave parabola. For the decision of differential equalizations of IV of order, that describe the axisymmetric vibrations of plates of variable thickness the methods of symmetries and factorization are used. The first are found three natural frequencies and the corresponding to them forms of vibrations are built for a circular plate with the hard fixing of internal contour. The results of calculation confirmed reliability of the worked out methodology and satisfactory exactness offered approach for tasks about the vibrations of plates of disk-type.
