摘要：
The accuracy of torsional fatigue test results for various drive spindles hinges on anti-twist technology. Initially, the defects of the existing anti-twist technology are analyzed, and subsequently, a cylindrical spring-based test torsion prevention scheme is proposed. Following this, the engineering design and calculation analysis of the elastic anti-twist device(EATD) are conducted, utilizing the relevant parameters of the torsion hydraulic cylinder intended for the torsional fatigue test of the main shaft parts of the aero-engine as the design input conditions. Ultimately, research summaries from calibration test and engineering verification test demonstrate that the EATD features a simplified structure due to the use of unit design, an efficient installation process that saves over 12 hours/person in time, and high accuracy achieved by several-fold increase in precision. Consequently, the cylindrical spring-based antirtwist technology offers great engineering application value. © 2024 Nanjing University of Aeronautics an Astronautics. All rights reserved.
