Summary:The invention provides a gearbox vibration response simulation analysis method, and relates to the technical field of gearbox vibration analysis. According to a digital twinning technology, a high-precision digital model of a gearbox is established, and an optimal working external force vector is generated; generating a second-order differential equation of vibration of each functional part of the gearbox according to a mass matrix, a damping matrix and a stiffness matrix of the gearbox, collecting data by adopting a sensor arranged on an actual gearbox component, generating a functional vibration vector index according to a generated external force vector in combination with the second-order differential equation of vibration of each functional part of the gearbox, and calculating the vibration of each functional part according to the functional vibration vector index. The vibration condition of each functional part of the gearbox can be reflected through the functional vibration vector index, the external f
