Structural Design and Optimization for Bracket of Passenger Airbag
The finite elements of the passenger airbag housing and bracket were meshed based on the geometry structure.The four node membrane elements were applied for the airbag housing and bracket.The passenger airbag housing and bracket modal analysis is performed.The strength of the bracket is analyzed.Reducing airbag mass and increasing bracket material thickness can improve the modal analysis results of the passenger airbag model,but the improvement effect is not so obvious.The modal analysis results can be improved significantly and the strength of the bracket can be enhanced through optimizing the design of the bracket structure.Using stiffener structure can significantly increase the first-order natural frequency of the passenger airbag model,avoiding reducing resonance and noise by adding felt.
