In order to ensure the normal use of the tensioned membrane structure, it is necessary to effectively detect the tension applied to the tensioned membrane surface. In this paper, a top-projection membrane surface tension measuring instrument with fixed boundary was designed. During the measure process, the force and the apex displacement were measured simultaneously to obtain the calibration curve group of force and abutment displacement. Compared with the traditional apex method, the measuring instrument eliminates the influence of the membrane structure boundary on the measurement results, and the measurement results were accurate and reliable. The correctness of the device is verified by numerical simulation and experimental results. Theoretically solved the technical problem of rapid measurement of membrane surface tension, and obtained stable results in actual measurement, thus providing a new method for membrane surface tension measurement.
