Integrated High Speed Video Becomes Mainstream for Automotive Test Applications
Abstract/Summary
Modern impact and test systems integrate video and data capture to provide a greater understanding of specimen failure modes.
High rate tests, such as performed on servo-hydraulically powered and instrumented impact test apparatus have, become widely used as a method of investigating the properties of materials and structures. As technology moves forward, so does the quality of the instrumentation, with gradual improvements in all areas: accuracy, dynamic range, bandwidth and sometimes cost.
The quantities most commonly measured during a high-rate event are force and acceleration, and the technologies for doing so are relatively mature. Sample deflection is also an important value that often needs to be determined, but this is not so easily done at the high rates of deformation typically encountered.
