In this paper, the theoretical analysis and experimental research method of combining dual - frequency vibratory compaction prototype operating parameters were optimized , the numerical simulation of the compaction process , the industrial applications of multi-frequency vibration the compacted theory and method to lay the foundation . Dual-frequency vibration amplitude and phase angle of the compactor further pilot study , obtained in a given medium conditions under frequency , amplitude and phase angle of the better value ; degree of compaction test , speed test and power test , as well as the response signal of acceleration and pressure in response to the signal processing and analysis , a comprehensive assessment of the performance of the prototype , and compared with the single-frequency vibration ; established on the basis of the pilot study , \soil \Experimental research shows stable performance of the prototype of the new design , the small amount of energy consumption of unit production , higher efficiency advantages .
