| Abstract: | Aiming at the failure of transmission mount bracket of a model of car,a dynamic model for powertrain mount is set up and a dynamic simulation is conducted to get the loading data.Then based on these data a finite element analysis and a corresponding continuum structure topology optimization on transmission mount bracket are performed.Finally,both the rig test and fatigue life prediction are carried out to validate the effectiveness and reliability of optimized design of transmission mount bracket. |
| Keywords: | Mount bracket Dynamics simulation FEA Topology optimization Fatigue life prediction |
