Wiper force distribution measurement system

Wiper can measure the force distribution of the wiper blade on the glass under various environmental conditions. This system can be used to research and develop wiper, blade and other products, so that the wiper can achieve better results. Wiper system includes USB data acquisition device, operation software, balance / correction device (model ා pb5d) and Tekscan's patented thin (0.004 in / 0.1mm) bendable sensor, which can measure the dynamic pressure distribution graph between driving, and the measurement result depends on different conditions such as driving speed, wind speed and wiper swing position. It is not easy to design a wiper that can clean the glass effectively. There are many limitations, such as different length, hardness, uneven pressure, curvature of glass bending, complex mechanical driving structure, and various wind pressure conditions, which cause many challenging problems in material selection and dynamic design. Wiper system can measure the whole rain The pressure distribution of the brush provides you with an important insight into how to improve your design and overcome these complex problems.
