摘要
为更好地了解不同细度、密度对柔性应变传感器性能的影响,采用有限元仿真的方法进行性能分析。首先,选用280D的镀银锦纶纱线,以1股、2股、3股织造5cm×10cm纬平组织物,同时对织物进行0%~60%拉伸性能测试。然后,通过显微镜测量织物线圈几何参数,采用Rhino建立织物几何模型,利用COM-SOL进行有限元仿真,模拟织物0%~60%拉伸应变过程。结果表明:随着合股数的增多,峰值电阻升高,电阻变化率波动增大。同时,有限元仿真方法与实验测试对比,平均误差不超过3%,最大误差不超过9%,证明了有限元仿真方法在性能分析的可行性与准确性。
In order to gain a better understanding of the effects of different yarn fineness and density on the performance of flexible strain sensors,a finite element simulation approach was employed for performance analysis.Silver-plated nylon yarn(280 D)was selected to weave 5 cm×10 cm plain weft fabrics using 1-ply,2-ply,and 3-ply yarns.Tensile tests were conducted on the fabrics under strain ranging from 0%to 60%.The geometric parameters of the fabric loops were measured using a microscope,and a geometric model of the fabric was constructed in Rhino.Finite element simulations were performed using COMSOL to model the fabric’s tensile strain process from 0%to 60%.The results indicated that with the increase in the number of strands,the peak resistance rose,and the fluctuation in the resistance variation rate became more pronounced.Furthermore,a comparison between finite element simulations and experimental results revealed that the average error did not exceed 3%,and the maximum error did not exceed 9%,which confirmed the feasibility and accuracy of the finite element simulation method for performance analysis.
