The Electrification of Material Moving Machines: An Overview of Opportunities and Challenges Regarding Noise
摘要
This paper explores the transition towards the electrification of hydraulic systems in material moving machines, highlighting both environmental benefits and the noise challenges posed by such technological change. With a focus on noise, the study examines the perceptual impact of replacing diesel engines with electric motors, which alters the noise profile of these machines. A survey assesses human responses to different hydraulic pump configurations in electrified setups, revealing significant variations in noise perception based on the specific design and the familiarity of the respondents with hydraulic sounds. The findings underscore the need for a nuanced approach to noise management in electric hydraulic systems, advocating for designs that consider both decibel levels and sound quality to enhance operator comfort and public acceptance.
