Car wipers, or should be called wipers, windshield wipers, are as important to drivers as seat belts and airbags, which can ensure a clear line of sight in bad weather. Therefore, the design of wipers has always been a particularly crucial step in the automotive development process.
In 1913, the American automobile manufacturing industry began to show exponential growth, and with the development of the automobile industry, people gradually began to realize the importance of wipers, but it was not until 1922 that Cadillac became the first manufacturer to include wipers as a standard part of automobiles.

As an important safety component of automobiles, current wipers can work at high temperatures (80 ° C above zero) and low temperatures (30 ° C below zero), resist acid, alkali, salt and other substances corrosion, and have a service life of 150,000 brush cycles (passenger cars).
Nowadays, the development of wipers has been relatively mature, but this does not mean that wipers will stop making progress. Factors such as different cross-sectional size designs, pressure distribution structures, pressure of wiper arms, and glass curvature will affect the performance of wipers. The SPI flexible fabric pressure distribution test system in the United States can form a professional solution specifically for whether the car wiper and windshield fit evenly, which is of great help to the study of wiper performance.
The sensor of the SPI flexible fabric pressure distribution test system consists of an array of resistive woven sensing units. The woven material is soft and has 120% or 158% ductility.
The SPI flexible fabric pressure distribution test system uses complex mathematical algorithms to intelligently separate signal from noise, and its electronic shielding technology can avoid the interference of the sensor by noise, temperature and humidity to the greatest extent.

As a visualization tool for pressure between contact surfaces, the SPI flexible fabric pressure distribution test system can be widely used in pressure distribution measurement and analysis in a variety of fields. It can perform static and dynamic measurement of pressure distribution on any contact surface, and display the contours and various data of pressure distribution in real time with intuitive and vivid two-dimensional and three-dimensional color images. The entire measurement process is recorded and stored, allowing users to view and analyze the measurement records at any time.
The SPI Flexible Fabric Pressure Distribution Test System uses objective tests instead of subjective tests to effectively reduce deviations. It can quickly and accurately reflect the pressure distribution between contact surfaces, and a measurement can be completed in a few minutes, which not only ensures the accuracy of the test, but also saves time, and reduces the impact of individual and environmental restrictions on the test results.

The SPI flexible fabric pressure distribution test system can measure the pressure distribution data exerted by the wiper on the windshield of the automobile, and can be applied to the fit test of the automobile wiper to display digital and visual data, which is convenient for analyzing the pressure of each contact point. Through repeatability testing, it can also provide effective data support for the design and function improvement of the wiper.
In addition, the SPI flexible fabric pressure distribution test system is also widely used in the design and development of car seats, door seals, seat belts, door handles, tires and other components.
With the development of sensing technology, telemetry and remote control technology, electronic technology and computer technology, the future stress testing system will also develop in the direction of high performance, low price, remote and higher degree of automation, and better assist the automotive industry.
