[0072] Based on the above-mentioned first embodiment, the door closing energy evaluation method of this embodiment, in the step S20, further includes:
[0073] Step S201: Input the compression load curve and compression amount corresponding to each discrete unit into the preset model to obtain the equivalent area of each discrete unit.
[0074] Step S202: According to the equivalent area of each discrete unit and the corresponding compression amount of each discrete unit, calculate the equivalent volume of each discrete unit by volume equivalent method.
[0075] Step S203: Summarize the equivalent volumes of the discrete units to obtain summary data, and use the summary data as the compression potential energy of the door seal.
[0076] It should be noted that the area of the closed figure is obtained by calculating the compression load curve and compression amount corresponding to the discrete unit obtained above, and the area is the compression potential energy corresp...

The invention belongs to the technical field of vehicle door closing performance, and discloses a vehicle door closing energy evaluation method and device, equipment and a storage medium. The method comprises the following steps: acquiring a compression load curve and a compression amount corresponding to each discrete unit of a vehicle door sealing strip; determining the compression potential energy of the vehicle door sealing strip through a preset model according to the compression load curve and the compression amount corresponding to each discrete unit; and detecting the vehicle door closing energy according to the compression potential energy of the vehicle door sealing strip. Through the adoption of the method, the accurate compression potential energy of the vehicle door sealing strip is obtained, and the influence of the compression force direction of the vehicle door sealing strip and the influence of the change of the deformation resistance of the sealing strip along with the change of the compression amount are eliminated effectively, so that the vehicle door closing energy can be evaluated more accurately.
Description
technical field [0001] The invention relates to the technical field of vehicle door closing performance, in particular to a method, device, equipment and storage medium for evaluating vehicle door closing energy. 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] In the prior art, the minimum energy for door closing is the kinetic energy applied to the door at the initial position to ensure that the door can be closed after overcoming the energy consumed in the c...
