Development Simulation

Off-highway machine and equipment manufacturers are working to lower their product’s noise level. Total radiated noise includes contributions from different sources including cooling fan, engine, transmission, muffler and the hydraulic system. In the following, the results of a methodology developed by Exa and Vermeer using a simulation tool to predict and optimise total noise for a horizontal directional drill are presented. Coupled with high-performance cloud computing, this method delivers accurate and complete noise analysis well within the short design periods typical of modern engineering project arcs.


Noise control treatments for directional drills and similar machines must be designed for high performance at the operator location, for less operator fatigue, and in the far field, for reduced neighbourhood and jobsite disturbance. Noise can be attenuated by the design of hood and chassis openings and the addition of silencers, acoustic insulation and louvers. Early...
