Abstract EN
The severity of gear noise response depends on the sensitivity of geared rotor system dynamics to the transmission error.
As gearbox design trending towards lighter weight and lower noise, the influence of housing compliance on system dynamic characteristics cannot be ignored.
In this study, a gear-shaft-bearing-housing coupled impedance model is proposed to account for the effect of housing compliance on the vibration of geared transmission system.
This proposed dynamic model offers convenient modeling, efficient computing, and ability to combine computed parameters with experimental ones.
The numerical simulations on system dynamic characteristics are performed for both a rigid housing configuration and a flexible one.
Natural frequencies, dynamic mesh forces, and dynamic bearing reaction loads are computed, and the housing compliance contribution on system dynamic characteristics is analyzed.
Results show that increasing housing compliance will decrease the system natural frequencies and will affect the dynamic bearing reaction loads significantly but have very little influence on the dynamic mesh force.
Also, the analysis shows that bearing stiffness has significant influence on the degree of housing contribution on system dynamic characteristics.
