Vehicle door closing air resistance energy acquisition method, device and equipment and storage medium

Abstract

The invention discloses a vehicle door closing air resistance energy acquisition method, device and equipment and a storage medium. The method comprises the steps that in the vehicle door closing process, a pressure curve of air pressure borne by a vehicle door changing along with time is obtained; according to a preset conversion strategy, the pressure curve of the air pressure borne by the vehicle door changing along with time is converted into a torque curve of the equivalent torque changing along with the vehicle door closing angle; an equivalent area is calculated according to the moment curve of the equivalent moment changing along with the vehicle door closing angle and the boundary, and air resistance energy is determined according to the equivalent area. Through the mode, the pressure curve of the air pressure borne by the inner surface of the vehicle door along with the time change is obtained, the torque curve of the equivalent torque along with the vehicle door closing angle change is converted, the equivalent area under the curve is determined according to the curve and the boundary, and the energy consumed when the air resistance in the vehicle cabin acts on the inner surface of the vehicle door when the vehicle door is closed is obtained. The problem that energy consumed by air resistance in a vehicle door closing cabin is difficult to accurately obtain in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method, device, equipment and storage medium for obtaining air resistance energy when a door is closed. Background technique [0002] With the development of the automobile industry, the requirements for the door closing performance are getting higher and higher. The indicators for evaluating the door closing performance mainly include the minimum closing speed of the door, the minimum closing force of the door, and the minimum closing energy of the door. Among them, the minimum closing energy of the door includes the information of the closing force and displacement of the door, which more accurately reflects the index of the closing performance of the door. [0003] The air resistance energy in the car is the most important part of the minimum closing energy of the car door. It is related to the volume of the car cabin, the area of ​​the door, the exhaust flow of the body...
