Accelerometer pendulum support assembly

摘要

In order to provide for accurate setting of a preload force on an accelerometer force responsive pendulum and to provide for rigid support for the pendulum, a pendulum support assembly is constructed with a flexure member that is attached at one end to the accelerometer frame. The flexure receives the preload force from a preload pin at the other end and has one pendulum axle bearing attached to it between the attachment point and the preload pin. In addition, the flexure includes a hinge portion located next to the attachment point that serves to make the flexure a statically determinate beam so that the preload force on the bearing can be accurately determined.
