The invention discloses a suspension adjusting method and system of a multi-axle train, the multi-axle train and a storage medium, and belongs to the technical field of train control technologies. An air cylinder of the multi-axle train inflates an air spring of a suspension through a preset air path, the multi-axle train further comprises a target air path connected with the preset air path in parallel, a normally-open electric control one-way valve is arranged on the target air path, when the electric control one-way valve is switched off, the target air path is not ventilated, and when the electric control one-way valve is switched on, the air cylinder inflates the air spring through the target air path. The suspension adjusting method of the multi-axle train comprises the steps that the running speed and the wheel rotating speed of the multi-axle train are obtained; calculating the sliding rate of each tire according to the driving speed and the wheel rotating speed; judging whether the sliding rate is within a preset range or not; if not, the electric control one-way valve is controlled to be closed, so that the height of the air spring is increased. The transverse stability of the multi-axle train can be improved, and the service life of the tires is prolonged.
