Design of Six-Axis Force Sensor and Analysis of Its Experimental Data

文中系统论述了一种六维力传感器的结构设计与分析过程,设计了该传感器的结构,采用有限元分析方法,分析了敏感区域的弹性形变量,确定了最佳敏感位置,解决了传感器敏感单元的贴片位置问题。由于该传感器要作为传动部件,因此分析和计算了扭转刚度,验证了结构设计的可行性。并以My方向的实验数据分析其重复性、线性度和耦合性,结果满足设计要求。文中对六维力传感器的设计和分析过程对一般传感器具有借鉴作用。

This paper described a six-axis-force sensor＇ s design and analysis. It designed its structure, and analyzed its property in ANSYS and found its sensitive area to build the transducer unit. As the sensor will be used as a part for rotation, rotation stiffness was analyzed and calculated which meet requirements. In addition, the senor＇ s performance such as repeatability, linear and coupling was analyzed based on the My vector data, which can meet the demands. The methods of the analysis and design of the sensor will have a good implication for the general sensors.
