The invention relates to a device for testing friction force of a counter weight steel wire rope in an airplane structure test and an estimation method. The device comprises a balancing weight (1), achain hoist (2), a guide pulley (3), a steel wire rope (4), a loading beam (11), a loading actuator cylinder (8), a loading actuator cylinder force transfer member (9), a test piece (10), and a straingauge (13). The device is characterized in that the test device is installed below a test bed beam (6), the upper end of the test piece (10) is fixed with the test bed beam (6), the lower end of thetest piece (10) is connected with the loading beam (11), and a counter weight steel wire rope system and the loading actuator cylinder (8) are symmetrically arranged at the left and right sides of thetwo ends of the loading beam (11). According to the device and the method in the invention, the implementation steps are clear and simple, and the engineering concept is clear. According to the device and the method in the inve
