Abstract

A technique for extending the life of disks of steam turbines is characterized. Repair technology for the rivet holes in the furcate latch assembly of a blade to a disk of a turbine is proposed. In the process of carrying out of numerical studies, the finite element method is used. The estimation of the residual durability of disks after repair is performed. Optimal variants of constructive changes in the geometry of the furcate latch assembly are established and recommended using the parameters of stability and durability.
