Structural Test Design and Interpretation for Aerospace Programs Training
Structural Test Design and Interpretation for Aerospace Programs Training Course Description
This three-day Structural Test Design and Interpretation for Aerospace Programs Training provides a rigorous look at structural testing and its roles in product development and verification for aerospace programs. The course starts with a broad view of structural verification throughout product development and the role of testing. The course then covers planning, designing, performing, interpreting, and documenting a test. The course covers static loads testing at low- and high-levels of assembly, modal survey testing and math-model correlation, sine-sweep and sine-burst testing, and random vibration testing.
• Identify and clearly state test objectives
• Design (or recognize) a test that satisfies the identified objectives while minimizing risk
• Establish pass/fail criteria
• Design the instrumentation
• Interpret test data
• Write a good test plan and a good test report
With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
Overview of Structural Testing
Why do a structural test? Structural requirements; the building-blocks verification process; verification logic flows; qualification, acceptance, and protoflight testing; selecting the right type of test; two things all tests need; test management: documents, reviews, and controls
Designing and Documenting a Test
Designing a test, suggested contents of a test plan, test-article configuration, boundary conditions, ensuring adequacy of a strength test, a key difference between a qualification test and a proof test, success criteria and effective instrumentation, preparing to interpret test data, documenting with a test report
Loads Testing of Small Specimens
Applications and objectives, common loading systems, test standards, case history: designing a test to substantiate new NASA criteria for analysis of preloaded bolts
Static Loads Testing of Large Assemblies
Introduction to static loads testing, special considerations, introducing and controlling loads, developing the load cases, example: developing load cases for a truss structure, be sure to design the right test!, centrifuge testing
Testing on an Electrodynamic Shaker
Test configuration, limitations of testing on a shaker, fixture design, deriving loads from measured accelerations, sine-sweep testing, sine- burst testing, understanding random vibration, random vibration testing, interpreting test data
Notching and Force Limiting.
Understanding notching, case history of notching without technical rationale, methods of notching, force limiting, designing a force-limiting fixture, NASA’s semi-empirical method, examples, modification during test, response limiting, manual notching.
Modal Survey Testing and Math Model
Correlation Test objectives and target modes, designing a modal survey test, key considerations, test configuration and approaches, checking the test data, correlating the math model
