Truck driving on uneven road surface can induce vibration, which will pass to skid, with vibration.If skid-mounted device structure has weak spot or brings resonance, it may lead to damage of skid-mounted device in the process of transportation.The frequency value of the first 16 steps of the natural vibration frequency of the skid mounted equipment is relatively low.It is suggested that the vibration frequency of the carriage should be kept away from this frequency range during vehicle selection and operation.After selecting the buffer material, the transportation system will drive at the speed of 40km/h on the road of level E, with the vibration frequency significantly reduced.It is suggested that the driving speed should not exceed 30 km/h when driving on the gravel road.When driving on the high-speed road, the vibration of the vehicle is small, so it is necessary to prevent the vehicle from rolling or sliding.In the station road, it is mainly to prevent the damage of the skid mounted device caused by the vibration,and the safety measures combining the control of the driving speed and the improvement of the packaging fixation shall be taken.In this paper, the vibration characteristics of the vehicle due to the road roughness, and the mechanical characteristics of the transportation skid are analyzed respectively, which provides a new method for the design and transportation safety of the skid mounted device in the future.
