MULTI-COMPONENT FORCE AND TORQUE BALANCES FOR WIND TUNNELS
Abstract
Starting from the German experience in the field of electrical measurement of mechanical quantities, one of the top application is the six-component measuring of the aerodynamic load torsor. For these complicated mechatronic devices, which have to measure six widely different components with the same relative accuracy, a complex mechanical and electrical analysis has been performed concerning the optimum positioning and connecting of the strain gauges, in order to increase the sensitivity and to compensate the disturbing influences. Four original strain gauged multicomponent balances for scale model testing were designed and manufactured having in view the improvement of the road vehicle and aircraft performances. Concrete data are shown in the four figures and tabularly summarized.
