| description | The invention discloses a mass-adjustable dynamic vibration absorber for electrical equipment and a design method of the mass-adjustable dynamic vibration absorber. The mass-adjustable dynamic vibration absorber comprises an elastic component, a main vibration mass body, a rigid component and an adjustable mass body, one end of the elastic component is fixedly connected with substation power equipment to be subjected to vibration and noise reduction treatment, and the other end is fixedly connected with the main vibration mass body; the main vibration mass is connected with the adjustable mass body through a rigid component; the adjustable mass body is movably arranged on the rigid component, the equivalent mass of the dynamic vibration absorber can be adjusted by adjusting the position of the adjustable mass body on the rigid component, and finally the resonant frequency of the dynamic vibration absorber can be adjusted. According to the dynamic vibration absorber, the mass center position of the vibrator of |
