    Abstract
  • To solve the vibration isolation problem of torpedo borne computer in complex mechanical environment, this paper proposes a joint optimization design method based on UG and ANSYS Workbench. A parametric geometry model is established by UG and imported into ANSYS Workbench for finite element modeling. Modal parameters of the original design scheme are calculated and compared with the modal test data to prove the correctness of the calculation model. Then the optimal objective function is determined based on vibration isolation theory, and optimization design of the vibration isolation system is carried out using multi-objective genetic algorithm. Compared with the original design, the optimization scheme reduces the maximum natural frequency by 12.9% and the frequency interval by 79.6%, and increases the effective vibration isolation frequency by 39.1 Hz.
