摘要: 曲面共形传感器在三维组件的结构健康监测领域十分重要。然而,传统转移印刷工艺很难保证传感器部署位置与取向的精度;因此,结合了五轴运动平台与直书写(Direct Ink Writing,DIW)工艺,直接在非展开曲面表面制备共形传感器阵列。首先,设计传感器打印流程并编写了运动控制算法。其次,在无人机桨叶表面打印了具有多层结构的传感器阵列来监测应变,并与有限元模型进行对比。结果显示监测数据与模拟数据在趋势上十分吻合,数值误差小于15 %,证明该传感器能够监测零件表面的应变。最后,在曲率更大的螺旋桨表面上打印了传感器阵列,表明该方案具有高适应性及广泛的应用场景。

Abstract: Fabrication of conformal sensors for curved surfaces is important in structural health monitoring of three-dimensional components. However,attaching sensors to a curved surface by transfer printing is difficult to ensure the accuracy of position and orientation. Therefore, a five-axis motion platform was combined with the Direct Ink Writing (DIW) process to directly printing conformal sensor arrays on non-expanded curved surfaces. Firstly, a sensor printing process and developed motion control algorithm was proposed. Secondly,a multilayer structure of sensor array was printed on a UAV blade to detect the strain,and the data was compared with a finite element model. The results showed that the monitoring data matches well with the simulated data in terms of trend and error is less than 15 %,proving that the sensor is capable of monitoring the strain on the surface of the components. Finally,the sensor array was printed on the surface of a propeller with greater curvature to illustrate the high adaptability and the wide range of application scenarios of the scheme.

Key words: curved surface fabricate, DIW, conformal trajectory, sensor array
