Abstract: The anti-vibration effect of wheeled child conveyances relates directly to the occupant safe. The anti-vibration structures of wheeled child conveyances were studied, and vibration sources, transmitting ways and actual vibration strength were analyzed. By measuring the vibration acceleration of typical wheeled child conveyances with different anti-vibration structures, it was verified that the anti-vibration effect of damping frame structure was better than that of damping spring and pneumatic tire.
