This paper deals with the vibration isolation theory of vibroactive objects: engines, generators, pumps, compressors, fans, piping, etc. A new design of vibration isolation suspension with quasi-zero stiffness is proposed. Its mathematical model for selecting its main parameters is obtained. Computer calculations are performed. They show that a significant shift of the natural frequency in the direction of low one in the given suspension in comparison with the support only on coil springs with the same static load allows one to reduce the coefficient of force transfer to the base at operating frequencies. The latter makes it possible to improve the vibration isolation of various technological objects, especially of large mass and operating at low frequencies. |
