NVH Test Engineer

Shall interact with required stakeholders at Cummins and gather necessary inputs required for NVH Test Support. His key responsibilities shall be as below:

• Obtains input and negotiates with Design, Thermal Sciences, Materials and Product Validation and delivers key structural performance parameters like motion, load, natural frequency, stress, design margin, life, sound power to Design and Product Validation.
• Makes decisions in the area of structural design (materials and their processing as well as geometry) that impact structural performance (motion, load, natural frequencies, stress, margin design, life, sound power) of components and systems
• Applies and improves testing, measurement methods and computer modeling processes that determine and estimate motion, load, natural frequencies, stress, design margin, life, sound power using tools such as vibration analysis, digital signal processing, instrumentation, strain gaging, ANSYS, FE-Safe, GT-Suite, and AVL Excite required to support the processes and enable high quality decision making.
• Provides independent leadership of smaller business impact projects or ownership of complex components, products, systems or services with greater elements of ambiguity over the senior or lead engineer level and with full accountability to the project team.
• Delivers independent execution of established and emerging work processes and systems, while still developing technology or product knowledge.
• Leads the development and improvement of work processes and systems across a functional discipline area within a business unit site.
• Coordinates and directs work amongst technicians and temporary student employees, assists in the transfer of knowledge to lesser experienced engineers through either indirect (scope of influence) or direct management of a small, local group of engineers.
• Provides support and guidance to influence technical direction within a project team and continues to develop proficiency in the competency areas critical to success in the role.
• Operates as a recognized specialist in vibration measurement and data processing.
• Lead/ support vibration related tasks for Fuel Systems development on various components for various VPI, Current product and PPT programs. Including but not limited to: Vibration measurement, Vibration data acquisition, Shaker test profile generation, Shaker test execution
• Lead/ support strain gage data acquisition tasks including but not limited to: Strain gage test planning (strain gage, selection, placement, and bridge configuration) Strain gage data acquisition, Data processing, Perform fatigue testing and subsequent duty cycle analysis.
• Test and fixture design support (working with lab technician to design test to mimic the loading conditions in the field)
• Test plan determination and documentation Working with lab technician to execute the test
• Generate test results, perform duty cycle analysis using Cummins standard processes
• Perform structural analysis (using ANSYS Workbench) on Fuel systems components/systems according to Cummins standard processes including but not limited to:
• Pressure fatigue analysis
• High pressure sealing and fretting analysis
• Overload analysis
• Modal and Modal scaling analysis
• DBJ (design for bolted joints)
• Wear and beat in analysis Etc.
• Work functionally with material science team, development engineers, quality team and suppliers to help improve designs based on Analysis/Test results.
