ATZ Off-Highway - Total Noise Solution for a Directional Drill

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.
