Research and Test Verification of Anti-twist Technology Based on Cylindrical Spring
The accuracy of torsional fatigue test results for various drive spindles hinges on anti-twist technol-ogy.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 in-put conditions.Ultimately,research summaries from calibration test and engineering verification test demon-strate 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.Conse-quently,the cylindrical spring-based anti-twist technology offers great engineering application value.
