A vehicle abnormal sound detection platform comprises a static platform, a movable platform and four branch kinematic chains, the first branch kinematic chain and the third branch kinematic chain are oppositely arranged in the first direction of the static platform, the second branch kinematic chain and the fourth branch kinematic chain are oppositely arranged in the second direction of the static platform, and the first direction is perpendicular to the second direction; the upper end of the first branch kinematic chain and the upper end of the third branch kinematic chain are connected through a common connecting rod, the middle of the common connecting rod is rotationally connected to a pin shaft on the lower surface of the movable platform, and the pin shaft is perpendicular to the lower surface of the movable platform. Two ends of the first branch kinematic chain are respectively connected with the static platform and the common connecting rod; two ends of the second branch kinematic chain are respective
