EDUCATIONAL INSTALLATION FOR THE STUDY OF RADIAL OSCILLATIONS OF CYLINDRICAL SHELL

摘要

The utility model relates to the means of training and can be used in the educational process to demonstrate the radial vibrations of the cylindrical shell. By changing the location of the additional support 7 along the cylindrical shell 1 and fixing it relative to the base 4, we are able to investigate the effect of the shell length on the frequencies of its own radial oscillations by changing internal overpressure in the housing with a rubber membrane, fitting the end of the cylindrical shell 1 and realizing fixing from th to the hinged support and rigid support, demonstrating the possibility of avoiding dangerous resonant modes kolebaniy.Tehnicheskim result is a visualization of the dynamic behavior of a cylindrical shell, which undergoes radial vibrations, and the influence on the natural frequency and the length of the sheath ways of avoiding dangerous resonant oscillation modes.
