S.E.A.T (Seat Effective Amplitude Transmissibility) index is used to evaluate ride comfort under vehicle driving condition. The proposed objective evaluation methodology uses several accelerometers to derive an objective index which is more reasonable than subjective evaluation. Moreover, a CAE (Computer Aided Engineering) methodology is proposed to obtain simulation results using the measured acceleration data at seat mountings as input conditions to seat system assembly. Finally, several case studies are conducted for maximizing ride comfort using the CAE model.
