In this paper, based on the joint laboratory of Mechanics Test Center of Nanjing University of Science and Technology and Walter+Bai, the PTFE coated fabric film material is taken as the test object, and the A/D signal exchange between the numerical substructure and the experimental substructure is realized by PMI serial port program, and the hybrid simulation static test is carried out. The phenomenon that the supporting structure of the frame is deformed due to the interaction in the tension process of the membrane structure is simulated, and then the unloading effect on the membrane surface is produced. The test results show that the communication performance of PMI serial port program is good, and the time consumption produced by signal exchange process can be ignored. The accuracy and stability of the hybrid simulation test system are verified by comparing the mixed simulation test results with the pure numerical simulation theoretical solution. Through the comprehensive analysis of the test data such as stress, strain, displacement, loading and unloading times, some suggestions are put forward for the design of membrane and frame composite structure.
