What are the responsibilities and job description for the CAE NVH Specialist position at DBSI Services, Inc.?
Job Title : CAE NVH Specialist
Location : Detroit, Michigan
Job Summary :
Specializes in enhancing vehicle comfort and performance by analyzing and mitigating noise, vibration, and harshness (NVH) specifically for complete vehicle and powertrain systems. This role uses advanced simulation tools to optimize NVH characteristics, focusing on road noise, wind noise, isolation, and transmissibility to improve ride quality and customer satisfaction.
Key Responsibilities :
- Conduct NVH simulations for complete vehicle and powertrain systems, identifying and reducing sources of noise and vibration using tools like NASTRAN, Abaqus, and LMS Virtual.Lab.
- Develop and refine NVH models for vehicle and powertrain components, including detailed analysis of engine vibrations, exhaust noise, and road-induced vibrations. Provide design recommendations to reduce airborne and structure-borne noise.
- Analyze road noise and wind noise contributions across various speeds and driving conditions, identifying areas for enhancement in body structure, seals, and insulation.
- Evaluate isolation and transmissibility for powertrain components, focusing on minimizing vibration transfer to the cabin through mounts, bushings, and chassis connections.
- Collaborate with design, powertrain, and body engineering teams to integrate NVH mitigation strategies across the entire vehicle, addressing specific areas like body-in-white, chassis, and powertrain mounting systems for optimized isolation.
- Perform virtual testing and validation for NVH performance under diverse driving conditions, including rough road surfaces, high-speed scenarios, and idle states, to evaluate isolation effectiveness and reduce cabin noise levels.
- Interpret simulation results to enhance specific NVH aspects, such as wind noise, road noise, and powertrain isolation, and provide actionable recommendations for improvements.
- Correlate simulation models with real-world testing data, refining predictive models for complete vehicle and powertrain NVH behaviors, including airborne noise transmission and vibration transmissibility.
- Document NVH analysis findings and develop best practices for continuous improvement, focusing on road noise reduction, wind noise management, vibration isolation, and transmissibility reduction across the vehicle and powertrain.
- Proficiency in NVH simulation tools like NASTRAN, Abaqus, and LMS Virtual.Lab for vehicle and powertrain NVH applications.
- Strong understanding of vehicle dynamics, road noise, wind noise, isolation, and vibration transmissibility.
- Familiarity with automotive NVH standards, best practices, and benchmarks for complete vehicle and powertrain systems.
- Experience in evaluating and optimizing body sealing, insulation, and component mounting for enhanced NVH performance.
- Founded in 1995
- Privately Owned Corporation
- Managing Partner Business Model
- Headquartered in New Jersey
- US Based Engineers Only
- Collaborative Team Approach
- Methodology and Process Driven
