| Title | Finite Element Model Updating and Thermal Analysis of Ventilated Disc-Brake Rotors | ||
| Keyword | |||
| Abstract | In most finite element studies, the finite element models are not verified but assumed to be correct. This assumption should be substantiated before conducting further finite element simulations. To achieve this purpose, the FE model updating technique can be adopted to correlate the FE analysis result to the experiment. In this research, experimental modal testing and finite element analysis on a ventilated disc-brake rotor were first performed, and then based on the test frequencies and mode shapes, FE model updating was carried out using geometric and material parameters as the updating parameters. The resulted FE models are capable of accurately predicting the dynamic behaviors of the disc-brake rotor and suitable for further design modification studies. For the thermal analysis, heat transfer coefficients on the surfaces of a rotor as functions of time are first estimated by CFD simulation, and then imported to a thermal analysis program as the boundary condition. Finally, the temperature distribution of the rotor can be calculated by finite element analysis. The simulation results show that vortices will arise in the vented passages of straight-vent rotors, which means less heat carried away and lower heat transfer coefficients. To implement thermal analysis on the rotor block using ANSYS Transient Thermal, to get the maximum temperature histories for the brake rotors. |
