Over 200 pre-launch orders for the Premier I aircraft from 26 different countries demonstrate the success of the new design and the Company expects similar success for its Horizon model. The article describes Honda's SEA model for both airborne and structure-borne transmission of road tire noise and vibration to the vehicle interior. The model also identified the dominant noise transmission paths. Vibro-Acoustic Sciences congratulates Honda on leading the movement to the AutoSEA process for automotive noise and vibration engineering in Japan. Caterpillar, the world's leading manufacturer of construction and mining equipment, diesel and natural gas engines and industrial gas turbines, has a long history of commitment to customer satisfaction through engineering excellence.
Every project begins with the specific needs of customers and aims to exceed their expectations.
While the noise control requirements of today's heavy machinery are mostly driven by industry regulations, Caterpillar is leading the way to address increasing expectations in comfort and ride quality, of which noise is a major factor. AutoSEA2 plays a central role in Caterpillar's quest to be the leader in heavy equipment noise control. Prior to acquiring AutoSEA in 1995, external SEA specialist contractors were required. AutoSEA technology has been focused on noise in operator cabs for heavy equipment, such as track-type tractors, wheel loaders and excavators among other things. Caterpillar uses the software to evaluate current designs and new product concepts, as well as new construction methods, such as the use of non-metallic materials.
