- Abstract:
- The accurate finite element model is very important to the dynamic design of the structure. In view of the gear transmission system of large mechanical equipment, a precise finite element modeling method based on hierarchical correction is put forward. The whole transmission system is divided into sub structure, based on the experimental modal frequency data for the target value, the finite element model of surface modification technology on structure model was modified based on the response, and identify the uncertain parameters in the model. The results showed that the modified frequency is close to the experimental value, the mode correlation coefficient MAC value above 0.84, shows that the parameter identification validity and accuracy of the finite element model can be improved obviously, verifies the feasibility of precise modeling method based on the idea of layered correction is applied to a large machine design and analysis of dynamic characteristics of gear transmission system of mechanical equipment the. Finally, the response characteristics of the integrated transmission system are obtained, which provides a theoretical basis for the subsequent dynamic analysis of the system.
