The dynamic vibration absorber can control the surface vibration of the equipment, but also cause problems of coupling frequency offset and noise reduction performance reduction. The dynamic vibration absorption technology of power equipment based on comprehensive optimization method is studied to realize the efficient control of low-frequency noise and minimize the noise radiation of equipment. Aiming to minimize the acoustic radiation of the target frequency of the equipment, the natural frequency and installation position of the dynamic vibration absorber are comprehensively optimized. Example verification shows remarkable effect of noise reduction by the system with comprehensive optimization. Being feasible and superior, the method can provide reference for noise reduction optimization., authors=GENG Mingxin^1,2, MA Jiangang^1,2, BAI Xiaochun^1,2, SUN Qiang³, SHEN Chen¹, WEI Xinyu⁴, authorsList=GENG Mingxin, MA Jiangang, BAI Xiaochun, SUN Qiang, SHEN Chen, WEI Xinyu, authorCompany=1.
