A vibration-absorbing power generation device based on the principle of inverse magnetostriction

Abstract

The invention discloses a vibration reduction and power generation device based on an inverse magnetostriction principle, and belongs to the field of vibration reduction and vibration power generation products. The vibration reduction and power generation device comprises a vibration reduction module, a vibration conversion module, an inverse magnetic power generation module and a battery module, wherein a main body comprises a base, a six-degree-of-freedom platform, a first top rod, a first fastening screw and a piezoelectric rubber vibration isolator, the six-degree-of-freedom platform is embedded into a part above the base, the first top rod and the first fastening screw are fixed on an upper surface of the six-degree-of-freedom platform, the piezoelectric rubber vibration isolator is encircled at an outer side, is in contact with the base and the upper surface of the six-degree-of-freedom platform and is fixed, and a stepped cavity is formed between the first top rod and the first fastening screw. The vibration reduction and power generation device is low in production cost, small in size and light in weight, is easy to fix and expand and can stand a severe vibration environment, and high-efficiency power generation is achieved. The device is relatively simple in structure and high in stability, and can be installed in an array way.

Description

technical field [0001] The invention relates to the field of vibration reduction and vibration power generation products, in particular to a vibration reduction power generation device based on the principle of inverse magnetostriction. Background technique [0002] With the development of industry, the problem of mechanical vibration is more and more concerned by the shipbuilding industry. Mechanical vibration not only causes a large amount of energy loss, but also causes fatigue of equipment and shortens its life. Nowadays, vibration energy harvesting technology has become a hot spot in scientific research, but the existing vibration power generation equipment is difficult to popularize due to low power and high cost. Therefore, it is decided to study a vibration-absorbing power generation device based on the principle of inverse magnetostriction. [0003] At present, there are four main methods of using vibration to generate electricity: [0004] Inverse magnetostrictiv...
