DESCRIPTION
Applus IDIADA is an independent partner for the automotive industry with extensive capacity for management and resolution of NVH development projects.
Tools for testing and simulation, a highly experienced team, integration within a whole-vehicle performance department and management network for global development projects provide us with unique characteristics to carry out successfully global NVH projects.
 
Applus IDIADA offers a wide range of activities that allow taking into account the NVH performance at any stage of the vehicle development project:
  • Vehicle concept and target definition
    • Benchmark measurement programs
    • Establishment of project targets – Target book
    • Analysis of design concepts
  • Development and testing
    • Design validation plans
    • Subjective assessments
    • Measurements and troubleshooting for the full-vehicle NVH performance
      • Interior noise and vibration measurements:
      • Road noise
      • Wind noise
      • Powertrain noise and vibration
      • Squeak and rattle
    • Exterior noise measurements:
      • Regulation fulfilment
      • Source contribution analysis
  • Measurements and troubleshooting for the system and sub-system NVH performance
    • Combustion noise
    • Intake and exhaust noise and vibration measurements
    • Door slam
    • Brake noise - squeal and judder
    • Tire noise
    • Noise from HVAC units, etc.
  • Measurements to support to CAE development and correlation:
    • Body-in-white and trimmed body modal analysis
    • NTF and dynamic stiffness measurements
    • Noise and vibration isolation measurements
    • Structural acoustic cavity modes
  • NVH target validation
  • Troubleshooting and tuning
  • Component validation
  • Exterior noise development
