NVH Full Vehicle FE Model Build Services
Understanding NVH
Noise, Vibration, and Harshness (NVH) are critical factors in vehicle design. NVH engineering focuses on minimizing noise and vibrations within the vehicle cabin while ensuring a comfortable and enjoyable driving experience. An NVH Full Vehicle FE Model is a virtual representation of the entire vehicle, which is used to analyse and mitigate NVH issues.
At Machweise Technology, we specialize in the development of highly detailed and accurate NVH Full Vehicle Finite Element (FE) Models. Our services are designed to assist automotive manufacturers and engineers in improving vehicle NVH characteristics and achieving an exceptional level of comfort and performance
Key Components of Our NVH Full Vehicle FE Model Services
We start by importing the vehicle’s Computer-Aided Design (CAD) data. Our experts ensure that the CAD geometry is suitable for analysis by cleaning up and optimizing it for NVH simulations
CAD Import and Clean-up
We start by importing the vehicle's Computer-Aided Design (CAD) data. Our experts ensure that the CAD geometry is suitable for analysis by cleaning up and optimizing it for NVH simulations
Component and Assembly Modelling
We create a detailed model of every component in the vehicle, including the chassis, body, suspension, powertrain, interior, and more. Our assembly modelling ensures that all components are properly connected, replicating the real-world vehicle structure
Boundary Conditions
We apply boundary conditions that replicate real-world scenarios, including road loads, engine forces, and other dynamic inputs, ensuring that NVH simulations reflect actual driving conditions
Finite Element Mesh Generation
Our team generates a high-quality finite element mesh to discretize the vehicle geometry. Mesh quality is essential to ensure accurate NVH simulations
Design Optimization
Our NVH modelling helps identify design changes and improvements to reduce noise and vibrations, resulting in a quieter and more comfortable vehicle and vehicle interior
Material Properties
Accurate material properties for vehicle components are assigned to accurately represent the physical characteristics of materials used in the vehicle's construction, such as metals, plastics, and composites
NVH Analysis
We use advanced CAE software to perform a range of NVH simulations, including acoustic analysis, vibration analysis, and noise source identification. These simulations help identify noise and vibration issues, allowing for design improvements
Modal Analysis
We perform modal analysis to identify the natural frequencies and mode shapes of the vehicle. This information is crucial for understanding the dynamic behaviour of the vehicle
Acoustic Modelling
We simulate the acoustic properties of the vehicle's interior, including the cabin, to predict and optimize noise levels and sound quality
Reporting and Recommendations
We provide comprehensive reports summarising the NVH analysis results and recommendations for design modifications to enhance vehicle comfort and performance
