摘要：
Thrust bearings of an aero-engine integrate outer ring of bearing and squirrel-cage as one part. For this special-shaped bearing, a new method for thrust bearing structure modification design and measurement method of bidirectional axial force was given. The modification principle of axial force measurement, equal bending moment structural design idea, structural mechanical model, strength calculation contrast analysis, strain gauge and full-bridge leading wire adhesion were introduced, and test result analysis of force-measuring ring was made. Results proved that the error between theoretical calculations and calibration test was less than 5%. In the field test run, bidirectional force-measuring rings could accurately identify the turning point for direction change of axial force simultaneously. This means the proposed axial force measurement method based on force-measuring ring has high value of engineering practicability. © 2020, Editorial Department of Journal of Aerospace Power.
