Abstract

The invention discloses a sliding elastic beam and spring combined nonlinear ultra-low frequency vibration isolator, which mainly comprises a sliding elastic beam with negative rigidity and a spring with positive rigidity, and is provided with a connection component and a supporting structure, wherein the spring is connected below the sliding elastic beam; the connection component is used for connecting the sliding elastic beam; the supporting structure is used for supporting the sliding elastic beam; the sliding elastic beam has negative rigidity during deformation; the spring is of positive rigidity; and the entire vibration isolator has the characteristic of near zero rigidity because of combination of the two elastic elements. The entire system, namely the sliding beam and spring combined nonlinear ultra-low frequency vibration isolator provided by the invention has the characteristic of approximately dynamic quasi zero rigidity, can be used for isolating vibration of ultra-low frequency and has an anti-impact effect.

Description

technical field [0001] The invention relates to a vibration isolator, in particular to a non-linear ultra-low frequency vibration isolator combined with a sliding beam and a spring, especially a vibration isolator with ultra-low frequency vibration isolation performance. Background technique [0002] Vibration and shock phenomena widely exist in daily life, industrial technology and national defense. Vibration and shock phenomena exist in the process of vehicle driving, machine tool operation, satellite launch, etc. Most of these vibrations have a negative effect on the performance of various equipment and personnel comfort requirements. Therefore, it is necessary to deal with these harmful vibrations and shocks. Quarantine. In addition, for the manufacture and measurement of precision instruments, such as the processing and manufacturing platform of semiconductor devices, and the detection of gravitational waves in large-scale laser interferometer gravitational wave observ...
