| description | Considering the complexity of the gearbox structure, the first six orders are identified by using the single-point excitation and multipoint response modal identification technology, and the modal confidence, namely, the modal identification accuracy is high. Based on the first six orders of the gearbox obtained from the test, a modal finite element calculation method considering both calculation accuracy and calculation efficiency is proposed. Subsequently, the topology optimization method is used to optimize the structure of the gearbox. After optimization, the deformation of the gearbox at different natural frequencies is reduced, which provides a new idea for the optimization design of the gearbox structure. |
