【Abstract】 A dynamic model for coupled vibration of a helical gear transmission system is developed,in which the flexional,torsional,axial and rotational motion are considered.The dynamic differential equation is gained.The vibration response of the transmission system in the accelerate box FH660 of wind power generators was calculated.At the same time,I analyzed the three dimensional mode using finite element method.The helical gear transmission system is simulated well.It provides effective method for dynamic design of the helical gear transmission system.更多还原
