Structural and Dynamic Systems Tech Specialists – Experimental #MN241

Cummins • Fridley, MN

1d

About The Position

This role involves conducting experiments to determine the structural performance of components and systems. The specialist will evaluate experimental equipment and methods, providing recommendations for improvement. They will use experimental results to validate designs against customer requirements and negotiate key structural performance parameters with various engineering teams. The position requires applying statistical methods, principles of noise and acoustics, dynamics and vibration, and fatigue and durability to analyze data, model relationships, and make data-driven decisions. The specialist will also define strategies for modeling, simulation, and analysis, utilizing computer modeling processes and solving complex product problems. Additionally, they will interpret test equipment specifications, manage the product life cycle, and independently execute work processes while developing technical knowledge. Research, design, evaluate, install, operate, or maintain mechanical products, equipment, systems, or processes to meet requirements are also key aspects of this role.

Requirements

• Conduct experiments to determine structural performance of components and systems.
• Evaluate experimental equipment and methods and provide improvement recommendations.
• Utilize results from the experiments to determine the validity of the design to meet the customer requirements.
• Obtain input and negotiate with Design, Thermal Sciences, Materials and Product Validation and deliver key structural performance parameters like motion, load, natural frequencies, stress, design margin, life, sound power to Design and Product Validation.
• Apply Principles of Statistical Methods to analyze technical data using descriptive statistics, probability distributions, graphical analysis, and statistical inference and models relationships between response and independent variables using analysis of variance, regression, and design of experiments to make rigorous, data-based decisions.
• Utilize the Principles of Noise and Acoustics and the Principles of Dynamics and Vibration to evaluate both air and structure borne noise, sound power levels, sound quality, rigid and flexible body motion, velocities, accelerations, friction, and wear.
• Apply Principles of Fatigue and Durability to determine life of components and systems via numerical modeling and physical measurements and evaluates component temperatures, natural frequencies, mode shapes, displacements, strains/stresses, wear and fatigue life to draw conclusions that influence design decisions.
• Make decisions in the area of structural design (materials and their processing as well as geometry) that impact structural performance (motion, load, natural frequencies, stress, design margin, life, sound power) of components and systems.
• Apply and improve testing and measurement methods that determine motion, load, natural frequencies, stress, design margin, life, sound power and tools such as vibration analysis, digital signal processing, instrumentation and strain gaging required to support the processes.
• Utilize hydraulic and electrodynamic shaker systems, servo-hydraulic load frames, and data acquisition instrumentation to perform vibration and durability testing, including sine dwell and random vibration tests, and develop power spectral density (PSD) profiles from field or operational data to replicate service environments for fatigue evaluation.
• Define the strategy for modeling, simulation, and analysis of systems and system elements by considering specifics of a given situation or nature of the system of interest in order to derive insights for making quality decisions.
• Apply computer modeling processes including Matlab and LabVIEW, nCode, Siemens Test.Lab and Windows/Linux operating systems for complex technical problem solving and decision making.
• Solve complex product problems using a process that protects the user, determines the assignable cause, implements data-based solutions, identifies systemic root causes, and recommends actions to prevent problem reoccurrence.
• Utilize knowledge with Product Function Test System Design to interpret test equipment specifications from test standards or lab customer requirements, and assess capability of the lab equipment against the requirements and support infrastructure.
• Manage individual part life cycle including design, procurement, validation, production and retirement.
• Deliver independent execution of established and emerging work processes and systems, while still developing technology or product knowledge.
• Research, design, evaluate, install, operate, or maintain mechanical products, equipment, systems, or processes to meet requirements.
