Acoustic Engineering for Construction Equipment

Noise Vibration and Harshness (NVH) are very important topics in the development of new construction equipment. Legislative requirements for operator's ear level as well as the comparison to competitor equipment in terms of noise and vibration as well as sound quality set very challenging targets. NVH optimization of complete vehicles in conjunction with trade-off discussions between NVH, costs, emissions and durability is one of the most challenging tasks in the development process.

AVL Approach

With latest NVH development tools and methodologies, NVH facilities and engineering capabilities, the AVL Acoustic Engineering team is well prepared to support our customers in solving their development challenges. Using a combined approach of simulation and measurement, we develop individual solutions for, and together with, our customers. Important topics that AVL supports in the field of acoustic engineering for construction equipment are:
  • Operator's ear level optimization
  • Mounting system layout and refinement
  • Intake/ exhaust system layout and refinement
  • Vehicle NVH analysis
  • Driveline behavior
