Job Requirements
Responsibilities
-
Perform Full-Vehicle NVH Simulations
-
Execute full vehicle-level NVH analyses for road, motor and thermal system loads for noise and vibrations including mode map and full vehicle sensitivity.
-
Build and Maintain CAE NVH Models
-
Develop high-fidelity finite element (FE) and boundary element (BE) models of body structures, trimmed bodies, and full vehicles using Altair Hyperworks and ANSA.
-
Post-Processing and Root Cause Analysis
-
Analyze modal, FRF, and acoustic response results to identify noise/vibration contributors and propose design changes.
-
Create animations, frequency response plots, and mode shape visualizations to explain vehicle NVH behavior.
-
NVH Issue Identification and Countermeasure Development
-
Identify root causes of NVH issues and develop design countermeasures, damping strategies, or isolation solutions using simulation-led evaluations.
-
Collaborate with Cross-Functional Teams
-
Work closely with body design, powertrain, chassis, and system-level teams to optimize component and system-level NVH.
-
Provide guidance to CAD and test teams for model updates and validation plans.
-
Prototype Support and Evaluation
-
Support prototype vehicle builds by ensuring NVH requirements are incorporated and validated virtually before physical tests.
-
Propose early-stage improvements for concept vehicles and monitor NVH performance during prototype evaluations.
-
Conduct Design Optimization and Trade-Off Studies
-
Apply DOE, DFSS, and optimization tools to balance NVH performance against weight, cost, and packaging constraints.
-
Standardization and Process Development
-
Develop and document standard operating procedures (SOPs) for full vehicle NVH modeling and simulation practices.
-
Contribute to the creation of best-practice libraries for reuse across multiple programs and platforms.
-
Design Reviews and Communication
-
Present NVH analysis results in design reviews and program meetings.
Translate complex simulation findings into actionable insights and recommend design changes to improve vehicle-level NVH
