Abstract
A vibratory compacting machine has a supplemental member resiliently mounted on the frame of the compacting machine. The supplemental member has a resonant frequency that is substantially equal to the operating frequency of the vibratory compactor and effectively reduces the frame vibration. As a result of reduced frame vibration, the present invention provides increased operator comfort and extended service life of electronic, electrical and mechanical components mounted on the compacting machine.
Claims6
A compacting machine comprising a frame, a material contacting member including means for compacting a densifiable surface, said material contacting member being mounted on said frame, means for vibrating said material contacting member at a predetermined operating frequency (f.sub.o), a supplemental member having a preselected mass (m.sub.s), and a plurality of resilient mounting members connecting said supplemental member to said frame, said mounting members having a spring rate (K) selected to cooperate with the mass (m.sub.s) of said supplemental member and define a resonant frequency (f.sub.r) characteristic of said supplemental member, said resonant frequency (f.sub.r) being substantially equal to the operating frequency (f.sub.o) of said material contacting member.
