The invention discloses a vibration isolation device. The vibration isolation device comprises a vibration isolation cavity outer wall; a vibration isolation cavity is defined by the vibration isolation cavity outer wall; the vibration isolation cavity is internally provided with a target protection object; the inner side of a bottom plate of the vibration isolation cavity outer wall is connectedwith a support spring; the other end of the support spring is connected with the target protection object; the vibration isolation cavity is filled with a self-adaptive vibration isolation material; and the support spring is at least partially embedded in the self-adaptive vibration isolation material. The self-adaptive vibration isolation material has an excellent damping effect, and achieves a major damping effect of the vibration isolation device, and single or continuous vibration impact can be greatly reduced; and the support spring achieves an auxiliary damping effect during severe vibration, and achieves a major supporting effect on the target protection object in usual. According to the vibration isolation device, the damping effects of the self-adaptive vibration isolation material and the support spring are combined, the damping effect of the vibration isolation device is greatly improved, and the vibration isolation device has an obvious transient impact load reduction effect and continuous impact load reduction effect through testing.
Description
technical field [0001] The invention relates to the technical field of shock absorption, in particular to a vibration isolation device. Background technique [0002] Vibration is an extremely common physical phenomenon in industrial production and people's life, and the harm it brings cannot be underestimated. In the field of industrial production, the vibration of processing machinery will cause structural wear and affect the processing accuracy; in the field of aerospace, structural vibration may cause failure of key components, which may lead to flight or launch accidents; in the field of transportation, vibration will affect the transportation of vehicles safety and comfort of passengers; while in civil construction, vibrations in bridges or buildings can cause fractures, collapses, and even casualties. [0003] Taking an earthquake as an example, an earthquake is a sudden and extremely destructive natural disaster that causes structures to vibrate, thereby affecting th...
