Research progress on milli-micro Newton level forcemeasurement technology of bionic prototype

Abstract

Depending on the excellent functional body structure obtained by the natural evolution, many animals have become bionic prototypes, which provide effective solutions for complex problems in the engineering field. The milli-micro Newton level force measurement technology of bionic prototype can provide the necessary testing instrument for revealing the locomotion mechanical mechanism of these bionic prototypes. Starting from the excellent functional characteristic of typical bionic prototypes, the research progress of milli-micro Newton level force measurement technology for quantitative characterization of the locomotion function and material physical properties of bionic prototypes was summarized. Especially, the principle and function of force measurement system with sensor, the principle and function of centrifugal movement force measurement system and the principle and function of image processing force measurement system were analyzed. Three aspects are pointed out some important aspects that bionic prototype milli-micro Newton level force measurement technology should focus on in the future:the force measurement system with sensor should improve the dynamic response characteristicsand test accuracy, in order to accurately characterizethe motion propertyof the biomimetic prototype; the centrifugal movement force measurement system shouldpromote the accuracy of test platform speed information collection and the imagedefinition of high-speed camera, in order to accurately characterize interaction between the micro-bionic prototype and material surface;theimage processing force measurement systemshould consider how to accurately extract micro-displacement information from images, in order to improve the test precision and accuracyof the force measurement system.
