| Abstract | Many machine design problems relate to the class of inverse problems, whose solution is reduced to the solution of systems of linear algebraic equations. The relation between the matrix con ditionality number of such systems and solution errors is shown in this article. The application of the least square method to improve the accuracy of solutions is justified. A method for providing the sta bility of solutions of systems of linear algebraic equations based on the use of additional information by increasing the number of measurements of initial parameters is proposed. The approach and statis tical algorithm for achieving a given accuracy of the solution of poorly specified systems of linear alge braic equations are developed. The results of using the offered methods for the identification of eccen tricities and elastic inertial parameters in the problem of decreasing the vibroactivity of the rotor of tur bine pump are given. |
