Optimal Design for Parameters of Buffer Foots on Laptop

The uniaxial compression test of the buffer foots on laptop made by different rubbers was carried out so as to obtain their strength parameters.A simple finite element model for laptop was established to study the acceleration response of hard disk in drop of laptop when the rubbers differed in shape,size,thickness and distribution of locations.And then,a whole finite element model was established to do the drop test analysis,verify the results of the simple model and get the optimal results.
