【Abstract】 In this paper, a strain-gauge balance with six components, which have been used in NF-3 wind tunnel, is redesigned by sequence quadratic optimization method. Under much the same layout scales and output str ains, the section modulus of the balance is increased by 4%-13% compared with t he original designed balance. Experiments indicate that its strength and accurac y of measurement will be better.更多还原
