摘要
Aiming at effectively analyzing on power transmission processing of herringbone gear trains system, reasonably estimating the gearbox structure vibration and noise, finite element model is put forward considering fluid-solid coupling of gearbox. Time-varying dynamic loads calculating from the Ref. [5] are applied on each center coupling point of bearing holes. Dynamic response analysis is carried out on the gearbox by the transient dynamic analysis module of ANSYS software, and structural vibration acceleration of the gearbox investigation nodes is estimated. Tooth dimensional optimization design with multiple dynamic targets is carried out by the adaptive genetic algorithm. Optimization results show the vibration acceleration of teeth meshing line direction and gearbox machine feet are both significantly reduced under given load condition. Herringbone gear transmission experiment testing system with closed power flow is set up to verify the theoretical analysis. In order to verify herringbone gear dynamic systems vibration transmission theory and tooth surface modification effects, teeth meshing line direction vibration is measuring through high precision angle encoders of Heidenhain, and vibration acceleration of bearing seat and machine feet are measured by accelerometer.
