PNEUMATIC GRIP SYSTEMS AND MATERIAL TESTING SYSTEMS INCLUDING PNEUMATIC GRIP SYSTEMS

摘要

An example material testing system includes: a pneumatic grip configured to grip a specimen under test based on a supplied pressure; and a processor configured to control the pressure supplied to the pneumatic grip by repeatedly: controlling a fill valve to increase the supplied pressure; allowing the supplied pressure to stabilize after each increase; and adjusting a pressurization time based on comparing an expected pressure increase to an actual pressure increase during the pressurization.
