Abstract
- Wear is the primary cause of damage to the bushing area of the Variable Stator Vane (VSV) mechanism. This paper presents an approach for predicting the wear-damage behavior of the bushing region to enhance the long-term effectiveness and safety of the VSV mechanism. The approach is based on an energy dissipation model and innovatively combines the FRIC COEF and UMESHMTION subroutines embedded in finite element software to perform wear simulations. The new approach takes into account the variation of the friction coefficient with normal load and sliding velocity and applies it to the wear simulation. The friction and wear models used in the simulations are based on the fitting of real experimental data. The simulation results are then compared with the wear results based on the Archard model. The results demonstrate that the new approach is more effective in simulating the wear of the bushing material. The study revealed that the contact stress between the upper and lower specimens decreases as wear behavior develops. Additionally, the wear on the surface disperses the distribution of the contact stress. [ABSTRACT FROM AUTHOR]
