A six-component force/moment sensor calibration stand
Abstract
A compact portable stand for calibration of multicomponent internal balances is described. The stand is designed to control/eliminate misalignments between load trains and the balance being calibrated; it generates forces and moments with pneumatic cylinders for all but rolling moment, which is applied with conventional weights. Load application control is discussed, and performance is analyzed. It is noted that the calibration stand has the ability to sense off-axis loads resulting from distortion/deflections due to the primary loading. Having sensed these off-axis loads, the system can be adjusted to minimize or eliminate them while retaining correct alignment of the primary load with the balance.
