Abstract: In order to accurately obtain the tension of the flexible cable network structure on the satellite mesh antenna, a contact cable net structure tension measurement method with two actions is proposed. In the process of measurement the influence of three-point bending of rope on the measurement results is eliminated, and the tension value of the pre-tension rope with fixed supports at both ends is determined. The design idea of tension measurement system is put forward, and the tension measurement system is designed, which has certain application value.
