In order to improve customer's door closing experience,top-down design and development of the sound quality of an electric vehicle's door closing are carried out.In the product design phase,target values about subjective and objective evaluation for door closing sound quality are set according to door closing sound quality data of the existing vehicle model and test analysis of the benchmarked model,the main parameters affecting the sound quality of door closing are summarized.In the prototyping stage,NVH sound detection equipment is deployed to test sound quality parameters and simulate user experience for subjective evaluation.For the problems revealed in the sound quality evaluation results in the prototyping stage,sound quality has been improved by adopting the following measures:increasing seal reaction force in the door seal strip,controlling door seal gap,optimizing door lock and increasing door window holding force,etc.Subjective and objective evaluation results show that door closing quality of this model has achieved the product definition objective.
