Structural Test Webcast Series

13 ratings | 3.23 out of 5
Read in | Print | PDF

National Instruments invites you to learn about current approaches to performing a variety of structural test applications. Learn ways to automate and speed up modal analysis; create custom fatigue life analysis systems; and perform faster, more reliable structural and physical test tasks. Sessions include walkthroughs of modal and fatigue analysis, an introduction to optical sensing, and future possibilities that new technology presents. Also learn best practices for building control and DAQ systems and managing all the data your test teams create. Finally, PCB shares key considerations for selecting a hammer, strain gage, and accelerometer for best test results.

 

Structural Test Webcast Series

 

Best Practices for Developing Structural Test Systems

Duration: 20 minutes

Designing a structural test system starts with deciding what requirements are necessary. Explore the concepts of signal conditioning requirements, data throughput needs, and other concerns of large and complex DAQ systems such as synchronization. Additionally, flexible platforms for measurement and control make software development and communication between hardware much simpler. Learn about NI tools that can meet the needs for these systems and the different approaches to integrating them.
Presented by Jim Black, NI Structural Test Business Development Manager, and Shea Clymer, NI Product Group Manager

Managing Your Data to Succeed in Structural Test Applications

Duration: 37 minutes

Structural test applications depend on large amounts of data recorded multiple times to evaluate and validate different design parameters. Being able to quickly access and visualize important content in that data is crucial to making timely decisions when performing structural test. Learn about recommendations for logging strain, acceleration, and microphone data, as well as tips and tricks for automating the parsing and presenting of the data with NI DIAdem and the NI Technical Data Management Streaming (TDMS) file standard.

How Optical Sensing Is Changing Structural Test Applications

Duration: 43 minutes    

Fiber optic sensors provide unique advantages over the ubiquitous electrical sensors used in most physical measurement systems today. Stable operation in the most demanding environments, along with the reduction of sensor wiring, are among the benefits delivered by fiber optic sensors based on fiber Bragg grating (FBG) technology. Learn what kind of measurement challenges and applications are being solved with fiber optic sensing, and how you can easily integrate FBG sensors into your next measurement system.

Walkthrough of Fatigue Analysis Based on Strain Measurements

Duration: 15 minutes

Understand the stress life method of fatigue analysis from strain measurement to lifetime evaluation procedures. See a real-time demonstration of a strain gage measurement. Then see an ASTEM E1049 cycle counting time domain implementation and compare its behavior with the frequency-based approach using power spectral density analysis to build probability density functions. Watch the measurements and analysis easily carried out in LabVIEW while understanding, but not having to carry out, all the underlying calculations.

Comparing Modal Analysis Techniques for Structural Test Applications

Duration: 24 minutes        

In this introduction, learn about the different modal analysis approaches possible, from basic peak picking in the frequency domain to continuous monitoring of time domain samples with a stochastic subspace identification approach. See examples of each approach being applied with a demonstration on how to use them in NI LabVIEW software.
