STAND FOR TESTING FLEXIBLE MEMBER Russian patent published in 2002 - IPC

FIELD: testing technology; testing torsion bars. SUBSTANCE: proposed stand has frame on which the following components are mounted: active grip connected with power drive, passive grip, flexible member twist angle indicator and backlash eliminator. Active and passive grips are provided with bearing supports. Bearing supports of passive grip are mounted for turn relative to their longitudinal axis. Twist angle indicator is made in form of two angular position sensors mounted immovably relative to frame and connected with active and passive grips. Backlash eliminator is made in form of rocker arm connected with passive grip. Mounted on frame are flexible pushers and rigid stops engageable with rocker arm. EFFECT: enhanced accuracy of measurements; possibility of testing torsion bars at different twist angles. 5 dwg
