Problems solved by technology

[0007] The domestic custom-made i-motion distributed pressure sensor has a sensing area width of only 15mm and a length of 900mm. Since the shape of the sensing area is too different from the general weight, when the weight exceeds 200g, the force of the weight cannot be adjusted. Directly all act on the sensing area, and the applicable range of the sensor, the weight used for calibration must reach more than 30kg, so the method of conventional weight calibration cannot be applied

Abstract

The invention relates to the mechanical metering device field and especially relates to the calibration metering device of a thin-film array-type distributed pressure sensing system. The device comprises a standard weight, a thin film array distributed pressure sensor used for detecting the standard weight, a calibration groove, a limiting clamping plate which is arranged in the calibration grooveand is cooperated with the calibration groove, and a silicone pad arranged between the calibration groove and the limiting clamping plate. A gap is arranged between the calibration groove and the limiting clamping plate. A calibration boss is arranged in the gap. The thin film array distributed pressure sensor is arranged between the silicone pad and the limiting clamping plate. The standard weight and the calibration boss are cooperated. Compared with a traditional metering tool, by using the device of the invention, the weight of a calibration weight can be applied more than 30kg, a calibration range is increased, the measurement range of the pressure sensing system is widened and the usage range of the thin film array distributed pressure sensor is enlarged.

Description

technical field [0001] The invention relates to the field of mechanical measurement devices, in particular to a calibration measurement device for a thin-film array distributed pressure sensing system. Background technique [0002] When testing the pressure distribution at home and abroad, the corresponding tooling is often used to improve the speed and efficiency of the test, but the effect is often unsatisfactory and the cost is extremely high: [0003] Citation 1: Lan Minguo introduced a Tekscan pressure distribution measurement system in the 4th issue of "Measurement and Control Technology" in 2002, "Using Tekscan pressure distribution measurement system in the tire industry for tire ground contact analysis" in the 9th issue of 2008, and Baidu Encyclopedia. Advanced pressure distribution measurement system, describing the principle and characteristics of this measurement system, and pointing out that its pressure measurement range is ±5% in accuracy, and the research and...
