✦ Synopsis

As automobiles become quieter, the noise of wiper blade rubber in motion may become a problem for passengers. To resolve this noise, especially the squeal noise, we constructed an equation of motion for the wiper blade vibration by observation and FEM stress analysis. Based on the derived equation, we discovered several important design and material items which can be utilized to reduce squeal noise.
