【 摘 要 】

The dynamic model of a dual power split coupling gear transmission is established by lumped mass method. The time-varying meshing stiffness of the model was solved by using the loaded tooth contact analysis (LTCA) techniques. Through using numerical calculation method to solve the dynamics equation, the natural frequencies and natural modes is obtained. The results show that the quadruple frequency phenomenon is appeared, and the distribution of natural frequency is reasonable. It is meet the design requirements. The relative amplitude is the largest between the nodes at 23 and 29 in the vibration mode curve of the fundamental frequency. The method above provides a theoretical basis and data support for its dynamic performance optimization design.
