A micro-propulsion measurement system and measurement method for a micro-miniature underwater motion device

Abstract

The invention belongs to the field of the underwater microforce testing, and specifically relates to a micro-propulsion measurement system for a microminiature underwater moving device, and a measurement method thereof. The micro-propulsion measurement system comprises a computer measurement and control system, a data collection system, a fine-tuning displacement system, a lever force amplification and decoupling system, a strain type microforce sensor and a clamping device. A micro-propulsion measurement system for the microminiature underwater moving device is established based on the straintype force sensor and a lever principle, the horizontal microforce needing to measure is amplified, and a pair of bearings are arranged on the lever, the stress on the lever can be only unidirectionally transferred due to the existence of the bearings, the decoupling of the force for measuring the object is realized, and the influence by the force in other directions is eliminated, thereby accurately solving the required micro-propulsion. The propulsion measurement system disclosed by the invention can online and quickly measure the micro-propulsion of an underwater bio-robot.

Description

technical field [0001] The invention belongs to the field of underwater micro-force testing, and in particular relates to a micro-propulsion measurement system and a measurement method for micro-miniature underwater motion devices. Background technique [0002] With the increasing scarcity of land resources, the exploration and development of marine resources has become an important issue for countries all over the world. Micro underwater motion devices have been used in the development and utilization of aquatic resources such as oceans, and in the exploration of seabed topography. Fish and other aquatic animals have evolved for more than 500 million years, and their shape structure and movement mode are very suitable for underwater survival. They have the characteristics of high speed, high efficiency, and low noise. Therefore, researchers have developed a variety of micro Small underwater sports device. However, the propulsion force received by micro-miniature underwate...

Problems solved by technology

Susceptible to temperature through these means; capacitive susceptible to interference from electromagnetic fields

Although the traditional force value measurement is usually reproduced by standard weights, the current small standard weight is 1mg (10-5N), when the weight is less than 1mg, there will be great uncertainty so that it cannot be used as a force value standard

So far, countries have not established a unified method for the measurement of small force values ​​(≤10-5N), and there is no standardized value transfer system for values ​​below 10N in China, so it is difficult to popularize the use of small force measurements
