摘要：
A vibrator comprises an upper, lightweight, honeycomb rocker plate suspended above a rigid, lower base by a pair of triangular truss rocker arms. A pair of rigid, parallel, spaced-apart stringers within the vibrator rise upwardly from the lower base. A rocker shaft extending between the stringers pivots the rocker arms near their midpoint. A motor secured to the base within the vibrator drives a spaced-apart flywheel assembly that is mounted with a crankshaft journaled between the stringers. The motor is coupled to the flywheel assembly with a drive belt extending between suitable pulleys. The flywheel assembly crankshaft terminates in spaced apart, offset portions that reciprocate connecting rods linked to one end of the triangular truss rocker arms that vigorously vibrate the rocker plate.
