(НТУ "ХПИ", 2003) Григорьева, П. П.; Лымаренко, Ю. А.; Шамровский, А. Д.
Blades and disks are the most loaded elements of gas-turbine engines. In view of the big complexity of a problem, research of their work demands application of the modern methods based on use of the computer. Thus discrete models, as in the best way adapted for such discrete device, as represent the computer, are very interesting. In the article the discrete model of a gas-turbine engine disk with blades is offered, allowing to take into account winding oscillations of blades together with movement of a disk. Use of symmetry of system allows to reduce a task about oscillations of system with the big number of degrees of freedom to a task with two and three degrees of freedom . All mode shapes of oscillations of the system are described
