Abstract

The invention relates to the field of vehicle manufacturing, and discloses a vehicle body design optimization method and device, a vehicle and a storage medium. The method comprises the steps of obtaining an NTF curve of vehicle body design; when the NTF curve has an over-standard peak value, acquiring an in-vehicle acoustic cavity modal shape corresponding to the frequency of the over-standard peak value; determining a problem panel according to the in-vehicle acoustic cavity modal shape; measuring phase information of the problem panel; calculating a matching degree between the phase information and a preset target phase of the problem panel; and determining optimization measures of the vehicle body design according to the matching degree. According to the invention, the problem that theNTF function of the vehicle body is difficult to optimize is solved, the NTF curve optimization process is simplified, the method is high in applicability and can be suitable for all stages of wholevehicle research and development, and the research and development efficiency of the whole vehicle is greatly improved.

Description

technical field [0001] The invention relates to the field of vehicle manufacturing, in particular to a vehicle body design optimization method, device, vehicle and storage medium. Background technique [0002] The NTF function (Noise Transfer Function, noise transfer function) mainly refers to the corresponding functional relationship between the input excitation load and the output noise. Noise, vibration and harshness performance) have a significant impact. [0003] However, when designing the car body, it is difficult to optimize the NTF function of the car body, and there are many optimization rounds, which greatly affects the development progress of the car. Contents of the invention [0004] Based on this, it is necessary to provide a vehicle body design optimization method, device, vehicle and storage medium for the above technical problems, so as to solve the problem of difficult optimization of the NTF function of the vehicle body. [0005] A car body design opt...
