Analysis of Gear Noise in an Automotive Front Wiper System

摘要

Windshield wiper in an Automotive causes a variety of oscillatory phenomena such as chatter vibration, reverse noise, motor noise and gear noise. This paper, especially, focuses on a research of gear noise because its mechanism of generation is still uncertain. The results of my experiments show that resonance of gear train is the main factor to increase gear noises in windshield wiper. It was also found out that this resonance has loading dependency. I would like to suggest a robust design consideration to reduce gear noises with these analysis results.
