The invention discloses a door sealing structure and an optimization design method. The vehicle door sealing structure comprises a sealing piece arranged at the bottom of a vehicle door, and the sealing piece is matched with a sealing face on a vehicle body to achieve sealing between the bottom of the vehicle door and the vehicle body. The sealing piece comprises a sealing retainer meeting the sethardness requirement, the bottom of the sealing retainer is provided with an inwards-concave arc face in the length direction, and the arc face is matched with a protrusion on a vehicle body sealingface. A soft sealing layer is laid on the arc face, and the soft sealing layer enables the arc face to be in tight coupling contact with the protrusion. According to the vehicle door sealing structure, external noise transmitted into passenger room space can be reduced, the comfort of passengers is improved, meanwhile, corrosion of dust, rainwater and the like to the vehicle door and parts nearbythe vehicle door is effectively prevented, and the service life of the vehicle door is prolonged.
