Solution of the mechanism of wiper blade rubber squeal noise generation

摘要

As automobile sound lessens, the squeal noise of wiper blade rubber may make drivers uncomfortable. To resolve the squeal noise, we established an equation of motion on the wiper blade vibration by applying part observation and FEM analysis of the inside stress. On the basis of the derived equation, we discovered some items about the material and the design which can be utilized to reduce squeal noise.
