Topography Optimization of Automobile Seat Belt Bracket

A finite element model of automobile seat belt bracket was built by Hyper Works. Through computer-aided analysis, it carried out that the original model maximum stress was 347MPa, which was more than the material yield strength 340Mpa. The original model needed to be optimized. The best distribution scheme of the ribs was determined by the topography optimization technique. After optimization, the maximum deformation of the automobile seat belt bracket was reduced by 36.7%, the maximum stress was reduced by 17.6%, and the strain energy can be reduced by 32.9%. The mechanical performance of the automobile seat belt bracket was improved and the optimization effect was achieved.
