Pressure suit joint analyzer

摘要

The invention pertains to a measurement system for simultaneously measuring torque and angular flexure in a pressure suit joint. One end of a joint (11) under test is held rigid. A torque transducer (31) is pivotably supported on the other movable end of the joint. A potentiometer (36) is attached to the transducer (31) by an arm (33). The wiper shaft (37) of the potentiometer is gripped by a reference arm (41) that rotates wiper shaft (37) the same angle as the flexure of joint (11). A signal is generated by the potentiometer (36) which is representative of the joint flexure. A compensation circuit (67) converts the output of the transducer (31) to a signal representative of joint torque.
