Abstract

The invention relates to vibration isolation pads in the field of vibration isolation and noise reduction, in particular to a modular local resonance type photonic crystal vibration isolation pad which aims to solve the problems that cycle materials of an existing photonic crystal vibration isolator are small in cycle number, unobvious in vibration isolation effect, and the work space is restricted. The modular local resonance type photonic crystal vibration isolation pad comprises a vibration input support, a main body support framework, a vibration output support, a plurality of vibration input support connection column bodies, a plurality of vibration output support connection column bodies and N levels of local resonance type photonic crystal assembles. The vibration input support is located above the vibration output support, each level of the local resonance type photonic crystal assembly comprises an upper vibration isolation support, a lower vibration isolation support, a plurality of vibration isolation connection column bodies and a plurality of local resonance type photonic crystal local oscillators. The vibration input support connection column bodies and the vibration output support connection column bodies are connected with the main body support framework respectively. The modular local resonance type photonic crystal vibration isolation pad is used for vibration isolation.

Description

technical field [0001] The invention relates to a vibration isolation pad in the field of vibration isolation and noise reduction. Background technique [0002] There are various vibration problems in the machinery industry and other industrial sectors, many of which are harmful vibrations. Excessive vibration and noise caused by vibration will pollute the environment and damage people's health. [0003] Vibration isolation (referred to as vibration isolation) is the most widely used vibration reduction technology in vibration control. The so-called vibration isolation refers to taking certain measures between the vibration source and the system, and installing appropriate vibration isolation equipment to isolate the direct transmission of vibration. The essence is to add a subsystem (vibration isolator) between the vibration source and the system. From an energy point of view, vibration isolation is to change the energy spectrum structure of the vibration source exciting t...
