Research on Verifying the Accuracy of Finite Element Analysis on the Steel Strips of Boneless Wipers

In order to verify the accuracy of finite element method for detecting the strain distribution trend on steel strips of boneless wipers, a series of measures were taken. The strain values of eight points evenly distributed on the upper surface of a steel strip were measured experimentally. A finite element analysis of the model of a steel strip was performed using ANSYS 18.0 to obtain the strain values of these eight points. Comparing the simulated strain values with the experimental measurements, it is found that the distribution trends of two is consistent, but the simulated strain value of each point is much smaller than the experimental measurement. The reason for this error is that the influence of the self-gravity of a steel strip in the experiment was not eliminated. In future research, the experimental method should be improved to eliminate the influence of the self-gravity of steel strips on the experiment.
