Исследование погрешностей расположения при сборке деталей газотурбинных двигателей с учётом неравномерности затяжки резьбовых соединений

Abstract

The paper presents the study of GTE details location uncertainty under the influence of non-uniformity of fixing efforts. To perform the research has been developed the calculation method. The methodology of calculation incorporated the use of the finite element method. Study has been carried out on the assembly sample consist of: a shaft, small rigid spacer and a disk. Has been considered dependences of shaft position mutual errors relative to the disk by taking into account the effect of the uneven tightening torque on threaded connections.
