Commercial Vehicles
In the development of trucks, light commercial vehicles, and buses, vibrations, oscillations, and acoustics (NVH – Noise, Vibration, Harshness) play a crucial role. These factors significantly affect ride comfort and have a substantial impact on occupant health, vehicle durability, and the environment.
Using state-of-the-art CAE methods and a deep understanding of NVH simulations, we support our clients in enhancing performance in these areas. We provide tailored solutions – from the precise design of individual components to the optimisation of the entire vehicle.
With our expertise, we help ensure that objectives related to cost-efficiency, performance, ride comfort, and sustainability are reliably achieved.
comfort and driver health
In the commercial vehicle sector, the vehicle serves as a workplace, so special demands are placed on interior comfort.
Our solutions reduce whole-body vibrations in the driver’s seat and hand-arm vibrations on the steering wheel, while also improving the noise level in the cabin.
Our service portfolio:
- Complete vehicle system modelling
- Influencing and coordinating individual components within the overall system to optimise vehicle comfort
- Time domain analyses- Hybrid modelling (considering measurement results in the simulation model)
- Definition of target criteria for driving comfort and overall vehicle acoustics
Structural integrity and Durability
Constant vibrations to load-bearing components, attachments, drive train and the load can lead to material fatigue and expensive damage.
We develop solutions that decouple sources of excitation, such as the engine, tyres or road surface, using appropriate measures. This prevents resonance in the overall system and ensures maximum durability, safety and reliability.
Our service portfolio:
- Static linear calculations of the frame, body and cabin to evaluate stiffness, global torsion and bending, and local connection points, as well as stress and strain distribution
- Dynamic, linear calculations to evaluate global and local natural modes and frequencies, as well as local dynamic stiffness
- Body structure optimisation in terms of function and weight (sheet metal thickness and shape)
- Stress analysis of individual components (e.g. brake lines)
- Functional optimisation of individual components (e.g. leaf springs)
- Optimisation and evaluation of accelerations and PSD signals (e.g. from electric or electronic components)
- Fatigue analyses
Noise Emissions
The noise generated by commercial vehicles affects passengers and the environment and can cause health problems.
Using our expert knowledge and the appropriate CAE tools, we develop the right sound profile for vehicle interiors and ensure that legal requirements are met.
Our service portfolio:
- Evaluation and optimisation of the sound emitted from the structural surface using the boundary element method (e.g., engine block, transmission housing, exhaust system, and air intake systems)
- Virtual transfer path analyses
- Low-frequency NVH analyses (engine noise, road noise, such as humming, rumbling, etc.)
- High-frequency NVH analyses (engine noise, gear noise, such as howling, etc.)
From initial concept to series production – we’re your reliable partner.
