Method and device for determining NVH target value of each order of rack and storage medium

The invention provides a method and device for determining an NVH target value of each order of a rack and a storage medium. The method for determining the NVH target value of each order of the rack comprises the following steps: acquiring background noise data of a whole vehicle; according to the background noise data and the vehicle model data of the test prototype, determining a vehicle NVH target value by combining a background noise database and predetermined data perceived by human ears; obtaining a corresponding relation model between vibration and noise of the test prototype; according to the vehicle NVH target value and the model of the corresponding relation between the vibration and the noise, determining the NVH target value of each order of a rack where the test prototype is located by adopting an NVH transmission model of an automobile part power assembly and the vehicle so as to determine whether the NVH of the test prototype is qualified or not. Therefore, the precision of the NVH target value
