Aeroacoustics Wind Tunnel Testing

The airframe noise generated by landing gear, flaps, slats, and other high-lift devices is a major contributor to aircraft acoustic emissions during approach and landing :

To minimize noise pollution around airports, engineers must evaluate and optimize acoustic performance as early as possible. Wind-tunnel tests validate prediction models before flight but incur high cost and lengthy preparation.

Simulation Dynamics uses advanced computational aeroacoustic (CAA) solvers integrated with efficient wind-tunnel procedures, delivering rapid, high-fidelity noise data without sacrificing accuracy :

▶ Reduced test setup time

Finite Element Analysis of Vibration Fatigue

Structural vibration can induce fatigue, durability issues, and undesirable user reactions. Uncontrolled vibrations may impair functionality and pose safety risks.

Vibration-fatigue simulations in the frequency domain predict material life more efficiently than time-domain methods under random loads such as wind and waves.

▶ Simulate shaker tests: random PSD, swept-sine, sine-dwell, sine-on-random
▶ FE models solved for frequency response & modal analyses
▶ Define vibration loads including temperature, static offsets, combined duty cycles
▶ Use fatigue loads for SN and EN lifetime predictions

These FEA-based vibration-fatigue workflows deliver accurate durability forecasts, optimize designs for longevity, and ensure safety under real-world loading conditions.

Our cutting-edge Artificial Intelligence & Machine Learning integrated development solutions combine technical excellence with business insight to deliver exceptional digital experiences.

We leverage modern frameworks with CFD & FEA solvers and cloud infrastructure to build applications that scale seamlessly with your industrial needs.

Ground Vibration Testing (GVT)

Airworthiness & GVT Certification

Ground Vibration Testing (GVT) is a critical FAA & EASA milestone, yielding experimental vibration data to validate and refine structural dynamic models for flutter prediction and safety-critical flight tests.

Performed late in development under tight schedules, GVT must be swift yet thorough. Modern lightweight structures and VTOL architectures introduce dynamic uncertainties, demanding precise modal testing to ensure compliance and safety for new UAM concepts.

▶ Calibrate FE models for flutter predictions
▶ Extract modal frequencies, damping, mode shapes
▶ Perform structural coupling with control systems
▶ Reduce risk of flight-test flutter

Aeroservoelasticity (ASE) integrates flexible structures, aerodynamic loads, and control laws. ASE models calibrated during GVT underpin accurate flutter analysis across the flight envelope.

NVH Analysis for eVTOL & Electro-Motors

FEA-based simulation in electromagnetic multiphysics environments delivers critical insights for Noise, Vibration & Harshness (NVH) analysis of electrical machines and transformers.

NVH is vital for hybrid/electric-vehicle motors, appliances, transformers and any application demanding quiet operation. Two-way transient magnetostriction coupling integrates magnetostrictive forces into mechanical models to predict acoustic noise.

Results from transient electromagnetic solvers generate force distributions that are mesh-element-accurate. Specialized co-simulation algorithms map these forces directly into mechanical solvers for harmonic and vibro-acoustic analysis.

▶ Transient EM simulation → force vector extraction
▶ Element-based force mapping to structural mesh
▶ Harmonic stress & modal coupling
▶ Optional acoustic analysis for noise prediction

To optimize NVH, our engineers use these force mappings to drive advanced vibro-acoustic simulations. Modal and harmonic stress responses reveal vibration magnitudes and generate waterfall plots for a full acoustic profile.

Vibroacoustics Performance Assessment

A true VTOL system design has complex challenges, particularly designing for a high thrust for hover while also reducing drag for cruise. In simple terms, you are designing a helicopter and forward-flying aircraft in the same product.

Vibroacoustic (VA) characteristics, namely sound transmission loss, overall sound pressure levels of aircraft panels made up of different materials such as aluminum, composites and fiber metal laminates can be analyzed with optimization approach for aircraft panels.

The investigation involves modeling of aircraft panels using finite element method (FEM) for low frequency, Boundary Element Method (BEM) for mid-frequency and statistical energy analysis (SEA) in high-frequency bands. To obtain the VA characteristics of the panels, twin chambers, namely source and receiver are numerically modeled, and the panels are placed in between them. This numerical study helps in understanding the VA behavior of aircraft materials and also minimizes the cost and time involved in conducting experiments.
