Title Case history: a study on the noise control for wheel loaders
Bibliographic information Nov.-Dec. 1990, Vol.35, No.3, p.85-94. Illus. 5 ref.
Abstract Sources of noise in 6 models of wheel loader manufactured in the People's Republic of China were identified. Antivibration mountings for the engine were designed, appropriate damping materials for sheet-metal parts were found, a sound-absorbing cab liner was devised, a better orientation for the muffler was found and the engine hood was isolated from the cab wall. Together with the sealing of holes and joints in the cab and hood, these measures reduced noise levels at the driver's seat by 23.8dB(A), to 82dB(A). The measures did not require any major changes in the design of the equipment.
