CONCLUSIONS 1. for supporting dynamic sensitivity analysis and parameter optimization parameters such as modulation operation, the proposed mode synthesis method is quite effective. 2. there is an optimal value of the bearing damping. by supporting optimal damping, the system can greatly reduce dynamic load imbalance in the level of response and support.
