    摘要： A vibrating mechanism for vibrating a vibration compacting roller with a variable amplitude includes a vibration generating shaft, a movable eccentric weight turnably disposed in the vibration generating shaft, and an eccentric weight driving unit for rotating the eccentric weight about a pivotal shaft transversely extending relative to the vibration generating shaft. To generate vibrations for the vibration compacting roller, a vibration generating apparatus including a vibrating mechanism of the foregoing type is substantially composed of an eccentricity signal generating unit, a vibration mode setting unit, an eccentric weight eccentricity quantity detecting unit, and an eccentric weight eccentricity quantity controlling unit. Alternatively, the vibration generating apparatus may substantially be composed of a forward/rearward movement lever neutral position detecting unit and an eccentric weight eccentricity quantity controlling unit. Otherwise, the vibration generating apparatus may substantially be composed of a running speed detecting unit, a running speed setting unit a running speed comparing unit, and an eccentric weight eccentricity quantity controlling unit. The eccentric weight eccentricity quantity controlling unit is usually composed of a hydraulic cylinder, a hydraulic pump, a connecting rod, and solenoid driven change valves. In addition, a vibration generating method to be practiced by operating a vibration generating apparatus of the foregoing type is also provided.
