Collins Aerospace is seeking an experienced Principal Dynamics Engineer who will provide support for the Aircraft Wheels & Brakes product line as it relates to managing the dynamic response to braking (friction induced vibration) and other sources of excitation due to product operation. You will support commercial and military product lines, with focus on leading root cause investigations into vibration issues and leading the resultant design mitigation efforts.  As part of this, you will interact with internal and external customers and collaborate with various global cross functional teams/groups.

This role will be onsite at our Troy, OH facility.

What You Will Do:

• Lead structural dynamics projects of aircraft wheels & brake to ensure that analytical assessment, dynamic test, system dynamic response, final report and documentation are prepared for internal and external customers.
• Create and validate structural dynamics models (modal analysis, stability assessment, transient analysis, etc.), using ANSYS Mechanical, LS-Dyna and other CAE tools.
• Determine the parameters of dynamics related dynamometer test programs for development and qualification based on Aircraft/program needs. Provide testing oversite for instrumentation, data acquisition, and data analysis.
• Update and validate finite element models by test data correlation.
• Provide design recommendations based on modeling and test results to understand and improve dynamic response as required.
• Resolve field/operational issues related to excessive vibrations using Root Cause and Corrective actions (RCCA).
• Lead technology development and analytical methods improvement by using latest CAE tools and experimental validation.
• Collaborate with multidisciplinary teams during product development, validation, and qualification processes while effectively prioritizing tasks, meeting deadlines, and ensuring clear communication in a fast-paced environment.
