Design Validation and Verification

Engineers commonly use data acquisition hardware and software to test that design prototypes meet their initial requirements and accomplish their intended purpose. This includes testing for reliability and accuracy, verifying product life cycle, establishing evidence that a product meets a user’s needs, or ensuring conformance to an industry standard. The following case studies illustrate the productivity, accuracy, and flexibility provided by NI data acquisition (DAQ) hardware and LabVIEW software for validation and verification.

High-Level Impact Testing for the Certification of Safety Helmets

Using NI CompactDAQ to develop a system capable of sufficient throughput to ensure that each helmet test is thoroughly and accurately documented.

“A system upgrade such as the one we required is a major budget consideration, and for this reason we were very deliberate in our search for a new hardware package.” – Jim Barnes, Snell Memorial Foundation, Inc.

Building a Plastic Biodegradation Monitoring System

Using NI LabVIEW software and NI CompactDAQ hardware to create an automated multiunit composting system (AMUCS) to monitor the biodegradation characteristics of biodegradable plastics in compost.

“Given the fact that we were building a complex system with many sensors, NI CompactDAQ proved to be invaluable and versatile in realizing our objectives.” – Mark Pickens, University of North Texas

Ventrac Tests Noise and Vibration of Compact Tractors

Using a portable data acquisition system based on LabVIEW and NI CompactDAQ modules to record the test parameters and generate a report based on the unit and configuration tested.

“Having the ability to use the microphones and accelerometer for additional tests on parts of the machine…helps pinpoint problem areas significantly faster and increases the overall value of investing in a flexible, high-quality system.” – Roscoe Lehman, VENTRAC by Venture Products Inc.
