At present

the optimization design of an aero-engine rotor is limited to single disk optimization

and the optimization needs to be performed by manual adjustment. In view of the convenience of aero-engine rotor data exchange between the optimization and model building software platforms and the reduction of manual adjustment

an automatic optimization method of multi-disk rotor structure of aero-engine based on UG and Workbench platform was proposed. Firstly

based on the UG platform

parametric geometrical modeling of multi-disk rotor structure can be made

and a standardized template was generated

in order to optimize the similar disk optimization problem. Then based on the Workbench platform

with APDL and Python redevelopment code

extraction of multi-disk rotor structures state variables and automatic optimization of process control were completed. The results of a numerical example showed that under the condition of satisfying geometrical and strength requirements

the mass of rotor was reduced by 33%

and the stress distribution was more uniform. And the method was proved to be of good stability and precision.
