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
