Diaphragm Flexures
Introduction
Diaphragm Flexures
As described in the “Test Setup Considerations” section, one or two diaphragm
flexures are used when large thrust and side loads are encountered on test setups
having both the rotary actuator and the reaction bracket rigidly mounted to the
reaction base. The flange adapter option is required to attach the diaphragm
flexure to the actuator. The flexure attaches readily to torque cells. The rotational
inertia of the diaphragm flexure must be included when determining the actuator
performance.
