Solutions and Products
As a go-to-partner for developing and producing innovative NVH solutions, we are continuously setting technology milestones, which innovate along market trends and customer demands. Global solutions, fuel efficiency, and weight and space savings are all buzzwords in our industry. But the automotive industry is fast-paced: Today, megatrends such as e-mobility, autonomous driving, and digitalization are presenting the entire automotive industry with enormous opportunities and challenges.
In addition to technical implementation, the changes particularly impact the comfort and ride experience of all passengers. The new market trends cause established and emerging customers to address new requirements on comfort, safety, efficiency and durability to ensure comfortable, relaxed and safe travel in an electrified, autonomous future.
We at Vibracoustic are able to constantly adapt to any market changes and to always provide smart answers to customer demands. Our team of experienced engineers can capably customize our products in order to help our customers to reach their goals, adding comfort to mobility — today and beyond.
Increased fuel efficiency is top of the agenda for all vehicle manufacturers. For some time now, Vibracoustic has lead the development of innovative replacement of traditional steel brackets and housings with thermoplastics and composites. To do this, we combine our rubber and plastics experience to ensure secure bonding and guaranteed durability. Current plastics applications include power-train mounts, strut mounts, suspension bushings, and torque roll restrictors.

As vehicles get smaller or incorporate more electrical sub-systems, space under the hood is frequently at a premium. Using our full system know-how we are constantly looking at ways to downsize our components without affecting comfort or performance. For instance, we integrate dampers into mounts or even using other existing vehicle systems to provide the mass. We also enhance our variety of different materials such as new composites or compounds or look at how we can change the geometry of the spring to allow us to maximize performance and minimize components.

Driving cost savings while driving comfort can be as simple as eliminating redundant parts, increasing durability, or simplifying manufacturing processes. It can also involve a higher tech solution such as Active Vibration Control. This active solution is designed to tackle multiple frequencies and as such can be used to replace the balance shaft, a very heavy and expensive damper.

Electric vehicles may be quieter, but their drive creates vibrations in a frequency range that is more unpleasant for humans. Combustion engines produce vibrations of between 20 and 400 Hz, while electric motors produce vibrations of over 10,000 Hz.
At the same time, previously unheard noises come to the fore, such as rolling and wind noise, or previously unnoticed noise sources like the air conditioning compressor.
The use of new NVH technologies specially developed for the requirements of electrically powered vehicles is required. This may result in completely different damping characteristics of the products used. New solutions will then offer the same, or even greater, level of comfort as in current vehicles. Highly robust chassis mounts and our innovative air spring systems for light vehicles are already responding to these new challenges.
Passengers can make productive use of their time, reading the newspaper or working if they have no longer to concentrate on traffic as the driver. However, this is one of the major challenges facing autonomous driving, as productive use of time is only possible if passengers are not battling with a feeling of discomfort. No matter how interconnected the systems are and how sophisticated the safety technology is, autonomous driving will only be really accepted if passengers can feel at ease and comfortable while being driven. Vibration control technology has an important role to play in this.
During a transitional period, it needs to take two very different scenarios into account. First, the classic scenario, with the chassis tuning focused on the driver. It defines the dynamic properties and the driving feeling that is so vital in the purchase decision. But once the vehicle switches to autonomous driving operation, this configuration needs to change completely. Disruptive noise is damped, with vibration and impact reduced. This comfort mode places the focus on passive passengers. This is a necessary paradigm shift for autonomous driving to be regarded as an enjoyable experience. Already today, switchable air spring systems offer a wide range of adjusting options.
Entertainment services, such as screens integrated into the seats, are another example. Here, vibrations need to be compensated by means of seat dampers to ensure a pleasant, smooth entertainment experience.
