Several Primary Problems in the Development of Dynamic Metrology

Dynamic metrology has achieved initial effects after decades of development. However, due to the complexity of engineering dynamic measurement, existing metrology technology shows its limitations in terms of theoretical framework, characterization of metrological characteristics, and application in engineering measurement, and its future development direction is a problem worthy of study and discussion. Aiming at the high-precision dynamic measurement requirements for engineering applications, dynamic metrology technology is comprehensively reviewed from the perspective of the entire dynamic measurement technology chain, and several primary problems are discussed and analyzed combining domestic and foreign relevant researches. The problems include definition and scope, value reproduction and traceability, calibration method, and application method in measurement domestic and foreign. Suggestions are given from the aspects of thinking mode of research and analysis, requirements of technology and method innovation, and deep-level cooperation. These analyses are expected to provide some reference for the future development direction of dynamic metrology.
