Abstract

The invention discloses a vehicle road noise analysis method and device and a storage medium. The method comprises the following steps: calculating a tread displacement-coupling acceleration transfer function according to an existing vehicle finite element model comprising a tire model, and obtaining a plurality of coupling accelerations when an existing vehicle runs at a constant speed; and calculating a tread displacement excitation signal, and calculating the road noise of the to-be-developed vehicle according to the tread displacement excitation signal and the to-be-developed vehicle finite element model comprising the tire model. According to the method, a tire model is added in the process of calculating the vehicle road noise, so that the precision of a finite element model is improved; the structural characteristics of tire parts in contact with the road surface are fully considered, so that the calculation result of the vehicle road noise is more accurate.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a vehicle road noise analysis method, device and storage medium. Background technique [0002] With the continuous improvement of people's requirements for vehicle ride comfort, vehicle manufacturers are paying more and more attention to the comfort performance of vehicles. Among them, the noise inside the vehicle generated during driving is one of the factors that affect the comfort of vehicles An important factor is that the sources of noise inside the car are diverse, including noise from the vehicle itself (such as engine noise), and noise from the influence of the external environment, such as the noise inside the car caused by road excitation during driving. That is, road noise. [0003] In order to effectively reduce road noise and improve vehicle comfort, some manufacturers will establish vehicle models for vehicle road noise simulation analysis during the vehic...
