In order to solve the problem that the dual-rotor system of aero-engine cannot avoid the critical speed, a model of dual-rotor system with inter-shaft bearing was established. Considering the influence of unbalance sensitivity, damper effect and the load effect of inter-shaft bearing, the tolerability evaluation functions of low-pressure and high-pressure rotor excited modes were constructed, the tolerability objective function and the constraint condition for optimization design on workable mode of dual-rotor were confirmed, and the optimization design method for the workable mode of dual-rotor system with inter-shaft bearing was established. It was found that compared with the traditional critical speed margin design criterion, the maximum amplitude of the disk of the dual-rotor system with inter-shaft bearing was reduced by 39.83%, the total mass of the shafting was reduced by 2.32%, and the external force of the fulcrum was reduced by 64.98% by using the optimization design method for the workable mode, indicating that the optimization design method for the workable mode of dual-rotor system with inter-shaft bearing was effective.
