AI Technical Summary
Existing wind tunnel balances cannot simultaneously meet the requirements of high sensitivity, stiffness, strength, and strain gauge fabrication within a limited space. In particular, they are difficult to accurately measure small loads when there are large load differences, and traditional methods cannot effectively coordinate the stress requirements of different functional areas.
The heterogeneous material sensitivity enhancement technology is adopted. By designing a combination of heterogeneous materials for the support beam and the measuring beam, the sensitivity is improved by using low elastic modulus materials while ensuring the strength of high stress areas. Combined with additive manufacturing and multi-stage aging treatment, metallurgical bonding of materials is achieved, and bridge-road combination formula is used to eliminate bridge interference.
It improves the measurement sensitivity and stiffness of the wind tunnel balance, resolves the contradiction between sensitivity, stiffness and strain gauge patching processability, and realizes high-precision multi-component torque and force measurement in a limited space, breaking the performance limit of traditional wind tunnel balances.
