Job Description

Noise reduction on cooling fans by optimizing the blade Aerofoil profile
Acoustics analysis report with design recommendations, these reports document the analysis of noise sources, their characteristics, and potential solutions Using simulations to find the best configurations for noise and vibration reduction, such as vibration isolators, tuned mass dampers, etc Participate in physical testing activities to validate the accuracy of their simulations and ensure their design recommendations are effective Actively seek opportunities to improve the software tools, methodologies, and processes used for aeroacoustics analysis and mitigation Will be working on the Cooling fan, Compressor noise reduction, sheet metal components and various acoustic materials

Key Responsibilities:

Perform NVH Simulation activities and deliver validated results with respect to design targets using CAE Tools Actran, Ansys Hyperworks etc
Create finite element models of individual parts using appropriate preprocessing tools to meet accepted best practices Use CFD tools coupled with acoustic solvers to predict the noise level of cooling Fan, and set up computational domains, meshing, boundary condition, and run transient simulations to capture acoustic phenomena Analyze simulation results to identify the Noise sources in terms of sound pressure levels, directivity pattern, and Frequency spect Simulate modal analysis as a system & individual parts to identify the natural frequency, mode shape & Damping characteristics Set NVH targets for the HVAC products and prepare NVH target achievement plan (Cooling Fan, Compressor, tubes & Structural parts) Perform Noise Transfer Function (NTF) & Vibration Transfer Function (VTF) and use various Acoustic materials Solve High/Mid/Low-Frequency issues in Component, sheet metal, Full system Levels (Vibration & Acoustics) Correlate simulation results with experimental data for further refinement Collaborate with multidisciplinary engineering teams to design complex HVAC products and systems to meet functional requirements for acoustics and vibration performance Perform optimization studies to make continuous improvement in performance requirements of structures Perform automation activities to drive CAE lead time reduction
