摘　　要：多维力传感器能够测量三维空间内多个方向的力和力矩,因此广泛应用于称重、机器人、机械加工、航空航天、医疗康复等领域,已成为近年来的热点领域。由于多维力传感器一般通过安装在弹性结构上的多个应变敏感元件来实现,为了保证传感器的精度与可靠性,需要对弹性结构和敏感元件进行深入的研究和设计。本文综述了多轴力传感器敏感元件和弹性结构的研究现状和发展趋势,并以此为基础对多维力传感器小型化发展过程中的关键技术问题进行了阐述和探讨。A multi-axis force transducer measures forces and moments in multiple directions in three-dimensional space.Therefore,multi-axis transducers popular in a wide range of engineering fields including weighing,robotics,machining processes,aerospace,medical applications etc.Measurement of multi-directional forces and moments is typically achieved using multiple strainsensitive elements mounted on a spring structure.Both the sensitive elements and the spring structure require careful consideration to design a force sensor for accuracy and reliability.This review explores multi-axis force transducer developments across sensitive elements and spring structures.On this basis,the key technical problems in miniaturization of multi-dimensional force transducer is also presented and discussed.
