摘　　要：本文以某型航空发动机压气机机匣法兰螺栓为测试对象,通过模拟预紧力0~25500N的压力实验,得出可靠的测试曲线,并计算得出检测值与实际值的误差为约1.6%。证明该智能垫圈在理论及试验阶段可以满足工程化应用的结论。This paper conducts experimental research on a smart washer that detects bolt pre-tightening force;Taking a certain type of aero-engine compressor casing flange bolt as the test object, a reliable test curve is obtained by simulating a pressure experiment with a pre-tightening force of 0-25500 N, and the error between the detected value and the actual value is 1.6% through calculation. Left and right;prove that the smart washer can meet the conclusion of engineering application in the theoretical and experimental stages.
