| Abstract: | This paper presents a six-component precision static calibration equipment,which is suitable to calibrate wind tunnel strain microbalances.With the system of high precision reset stage and TV, the equipment can implements microbalance body axis calibration in five components;With precision transition of the force,the equipment implements accurate loading for the microload in horizontal. This paper also analyzes the general loading precision and influencing factor for three components balance.At the same time, we calibrate the three components mirobalance with this equipment. The calibration result is presented and compared with those of the other type balances. |
