应变天平的输出信号较小，安装和信号连接环节较多，吹风试验过程中故障较频繁。故对其信号进行合适的调理，使用适当的电信号校正技术，即用电的方法模拟天平所受的载荷，对解决天平使用过程中的问题，迅速诊断故障，提高天平以及风洞测力试验精度和准确度都有重要的意义。 The output signal of the strain gauge is smaller, more links are installed and connected, and the faults are more frequent during the blowing test. Therefore, the appropriate signal conditioning, the use of appropriate electrical signal correction technology that is used to simulate the balance of the load on the balance, the solution to the problem of the use of the balance to quickly diagnose the problem, raise the balance and wind tunnel force test Accuracy and accuracy have important implications.
