一种天平校准系统的体轴系载荷换算方法
By using a laser displacement sensor to measure the displacement and angular displacement of the balance loading head, combined with the length of the force generator pull wire and the mass of the weights, the actual load of the balance in the body axis system is calculated. This solves the problem of coordinate system non-coincidence during balance calibration, and realizes a high-precision load calculation and a low-cost calibration system.

AI Technical Summary
During static calibration of a wind tunnel balance, the coordinate system of the balance load does not completely coincide with the ground coordinate system, leading to load calculation errors. Existing compensated body axis calibration systems are complex to design and costly.
A laser displacement sensor is used to measure the displacement and angular displacement of the balance loading head. Combined with the length of the force generator pull wire and the mass of the weights, the actual load of the balance in the body axis system is calculated, which simplifies the structure and improves the accuracy.
It improved the accuracy of balance calibration, reduced design and construction costs, simplified the structure, and increased work efficiency.
