Applying Mathematical Package to Numerical Method of Solving Shaft Oscillation Problem with Disks

One of the forms of numerical solution of the problem of finding frequencies of free torsional oscillations of a shaft with disks is considered in the paper. A practical solution to the problem is given using the matrix form of the numerical method. On the example of a shaft with five disks, an example of using a matrix shape for calculating the vibration frequencies of the shaft is considered. The algorithm for solving the problem has a software implementation in the Maple mathematical package.
