Vibration noise contribution analysis method based on dynamic force recognition and vehicle

The invention discloses a vibration noise contribution analysis method based on dynamic force recognition, which comprises the following steps: S1, determining a target point of a vehicle to be detected, and arranging a sensor at the target point; S2, testing a to-be-tested vehicle based on the driving scene, and collecting working condition data GR collected by a sensor; S3, disassembling the suspension of the to-be-tested vehicle, and installing a suspension replacement part made of metal materials at the position wherein the original suspension is located according to the set torsion value; S4, testing the to-be-tested vehicle after the suspension is detached by adopting a hammering method to obtain a frequency response function HR from the suspension mounting point to the target point; S5, establishing a dynamic load target function according to the working condition data GR and the frequency response function HR, and solving a dynamic load F of the suspension attachment point by using an iteration method
