Work History
NVH Engineer
NV Dynamics
01.2023 - Current
- Conducted experimental modal analysis and vibration testing on monorail structural beams, utilizing advanced instrumentation and Siemens Simcenter Test.Lab to extract modal parameters, perform ODS analysis, and validate FEM predictions for structural integrity and design optimization.
- Led frequency response testing of MG stators at an industrial plant, managing the complete setup with synchronized multi-channel DAQ systems, calibrated tri-axial accelerometers, and controlled hammer excitation. Directed test planning across multiple stator levels, ensured accurate data acquisition, analyzed frequency response functions (FRFs), and validated structural dynamics performance. Delivered comprehensive project data package while meeting client specifications and quality standards.
- Conducted metro rail projects, including PITCMRL, GMRCL, and BMRCL, focusing on assessing noise and vibration levels in tunnel sections and viaducts. The objective was to evaluate the severity of noise and vibration, and quantify them according to relevant standards.
- Assessed the effectiveness of noise and vibration on a cable repair vessel to verify compliance with the requirements of the IMO and COMF class. Created reports summarizing test results, and recommending solutions for identified problems.
- Served as a primary member in vibration analysis of a motor and fluid coupler assembly at a steel plant, handling instrumentation setup, vibration data acquisition and processing of spectra to diagnose unbalance, misalignment, and thermal gradient effects. Provided inputs for corrective actions including motor balancing, alignment checks, and multi-plane balancing to enhance equipment reliability and performance.
- Trained junior engineers and technical staff on advanced NVH concepts, including sound intensity measurements, experimental modal analysis, operational deflection shapes, and vibration diagnostics, while guiding them through company-specific processes and best practices.
- Researched and applied multiple ISO standards such as ISO 3744, ISO 9614, and several others related to sound power, intensity, and vibration measurements, while also evaluating advanced data acquisition (DAQ) systems to improve accuracy and efficiency in NVH testing and analysis.
