Abstract

At present, some methods for measuring the surface tension of membrane structure are applied to engineering practice. But there are some defects happened in the engineering practice. This paper proves the partial boundary of the fixed membrane surface. The natural vibration frequency of the membrane surface is only related to the membrane surface tension. Based on this principle, a magnetic clip-type membrane surface fixed boundary fixture is designed. A method for measuring the tension of the membrane surface tension by measuring the natural vibration frequency of the inner membrane surface of the fixed boundary is proposed. The finite element method was used to analyze the vibration frequency of the fixed boundary membrane under different tensions. The vibration frequency of the fixed boundary membrane under different tensions was measured by experiments. The simulation results were compared with the experimental results, and the accuracy of the method was verified. Through this method, the calibration result of the small sample on the calibration table can be used for the tension measurement of any boundary condition in the actual project and the material film structure, which is in accordance with the requirements of simple operation, wide applicability and high measurement precision in engineering practice.
