[0031] In some embodiments, the generating the structural stability score of the virtual high-voltage connector based on a preset structural stability scoring method comprises the following steps: Perform finite element segmentation processing on the virtual high-voltage connector to obtain multiple finite element units corresponding to the virtual high-voltage connector, record the first volume corresponding to each of the finite element units, and generate the first coordinate point corresponding to each of the finite element units; specifically, for each of the finite element units, measure the first volume of the virtual liquid required to fill the finite element unit with the virtual liquid, use the required first volume of the virtual liquid as the first volume corresponding to the finite element unit, construct a three-dimensional rectangular coordinate system at a designated point on the virtual high-voltage connector, and for each of the finite element units, determine the coordinate point of the center of the circumscribed sphere of the finite element unit in the three-dimensional rectangular coordinate system as the first coordinate point corresponding to the finite element unit; After controlling the virtual high-voltage connector to run for a preset time in the virtual application scenario, recording the second volume and the second coordinate point corresponding to each of the finite element units; it should be noted that the method for recording each second volume and the second coordinate point refers to the method for recording the first volume and the first coordinate point, which will not be repeated here; The structural stability score is generated based on the first volume, the first coordinate point, the second volume and the second coordinate point corresponding to each of the finite element units.

[0032] The step of generating the structural stability score based on the first volume, the first coordinate point, the second volume and the second coordinate point corresponding to each of the finite element units comprises the following steps: For each of the finite element units, calculating a volume difference between a second volume and a first volume of the finite element unit, and calculating a distance value between a first coordinate point and a second coordinate point corresponding to the finite element unit; Determining whether a maximum volume difference among the volume differences is greater than a preset volume difference, and determining whether a maximum distance value among the distance values ​​is greater than a preset distance value; If the maximum volume difference is greater than a preset volume difference and / or the maximum distance value is greater than the preset distance value, determining that the structural stability score is infinitesimal; If the maximum volume difference is not greater than the preset volume difference and the maximum distance value is not greater than the preset distance value, Calculating the structural stability score; wherein, Score the stability of the structure, is the standard deviation between the volume differences, is the maximum volume difference between the volume differences, is the standard deviation between the distance values, is the maximum distance value between the distance values.

[0035] The method provided in this embodiment gives a conclusion that the shielding performance score is infinitesimal when the maximum magnetic field strength in the magnetic field strength curve is greater than the preset magnetic field strength, which helps to avoid adverse effects during high-voltage operation due to improper material selection. When the maximum magnetic field strength is not greater than the preset magnetic field strength, the shielding performance score is calculated based on the inverse of the maximum magnetic field strength to obtain an accurate and quantifiable shielding effect evaluation result.

[0036] In some embodiments, the generating the thermal management performance score of the virtual high-voltage connector based on a preset thermal management performance scoring method comprises the following steps: After controlling the virtual high-voltage connector to run for a preset time in the virtual application scenario, obtaining a temperature distribution map on the surface of the virtual high-voltage connector; specifically, obtaining the temperature distribution map through a preset virtual infrared camera device; For each pixel of the temperature distribution map, a temperature value corresponding to the pixel is obtained; specifically, for each pixel, a color value of the pixel is converted into a temperature value corresponding to the pixel based on a preset color value-temperature mapping function; Determine whether the maximum temperature value among the temperature values ​​is greater than a preset value; If so, determining that the thermal management performance score is infinitesimal; If not, pass Calculating the thermal management performance score; wherein, Score the thermal management performance, is the standard deviation between the temperature values, is the maximum temperature value among all temperature values.
