Abstract
This paper describes a co-operative programme sponsored by TRRL which has produced heavy diesel engined articulated vehicles having considerably lower external and internal noise levels than vehicles in current operation. The other organizations involved were Fodens Limited, Rolls-Royce Motors Limited, Leyland Vehicles, MIRA, ISVR and NEL. The work was directed at reducing the noise levels from the engine, exhaust and cooling systems, tyre-road surface interaction, and the transmission of noise into the cab. The environmental background to the project and its relation to future legislation on vehicle noise is considered as well as the bases for the technical solutions evolved.This publication has 0 references indexed in Scilit:
