Automotive Wiper Blade Pressure Consistency Measurement

Automobile tires need to test the tire grounding pressure and grounding area when leaving the factory, and the conventional testing method uses ink coor- dinate paper measurement. By scanning the ink on the coordinate paper, using CAD software to calculate the grounding pressure of the tire. Has a cer- tain degree of effectiveness, but the operation is cumbersome longtime, low test efficiency. Now we use our tire grounding pressure distribution measure- ment system for tire grounding area testing.

The thin-film sensor was precisely fixed in the test area of the machine, after which we securely mounted the qualified wiper on the clamping jaws. By ap- plying a uniform pressure of 50N to the midpoint of the wiper through the pressure device, the sensor quickly and accurately reads and records the pressure data of each part of the wiper rubber strip, providing a reliable basis for subsequent analysis and optimization.
