Mirthinti, D., Sahrawat, D., and Dang, R., "Investigation on Wiper Motor Noise and Measures for NVH Performance," SAE Technical Paper 2017-26-0207, 2017, doi:10.4271/2017-26-0207.
In automobile, NVH has been playing an important role in defining the overall quality of the vehicle. Continuous efforts are being put in globally by engineers to make the travel experience as comfortable as possible for both commercial and passenger segment vehicles. The front wiping system being a critical safety feature in an automobile is one of the sources of structural vibrations/noise due to numerous moving child parts. Therefore, the layout of the wiper motor in the vehicle is an important aspect of Vehicle NVH. These vibrations and noise levels become more pronounced if the wiper motor is mounted inside the passenger compartment, a layout that is commonly seen in commercial vehicles.This paper focuses on measures to improve the NVH while having the layout of the wiping system inside the passenger compartment of the vehicle.
