The pressure in NVH engineering is enormous; legislation continues to dictate ever-tougher noise and vibration limits; marketing wants to maintain core brand values but at reduced cost; customers demand products that are better, more refined. Yet at the same time, developing components, subsystems and the complete vehicle to the required levels of NVH represents one of the most complex aspects in automotive development. Full-vehicle NVH performance – the comfort and the sound quality that the driver will actually experience – is the result of the complex and multi-physics interactions between the multiple subsystems and components in the vehicle.
LMS Engineering offers a unique combination of advanced competences, dedicated processes and practices and innovative technologies that support vehicle development teams in optimizing the NVH performance of their designs. LMS can take full development responsibility for vehicle NVH, from concept to full vehicle, focusing on solving specific NVH shortcomings in newly developed or existing vehicles. LMS also assists NVH engineering teams in optimizing their own processes and practices. LMS Engineering has a track record in delivering solutions that are cost effective, take manufacturing restrictions into account, and are validated against possible conflicts with other key attributes like ride & handling, durability or crash.
