Abstract：Abstract: Considering the importance of the mechanical properties for the rubber-like material on the water-seal design, Mooney-Rivlin formula and Three Ogden formula has been applied in the processing experimental data of uniaxial tension test, uniaxial compression test and pure shear test. The nonlinear calculation for the free extension of pressure-filled telescopic water seal has been done by using the fitting parameters from the both formulas. Then the comparative study between the calculated results and test results has been carried. The results show that Three Ogden formula is better than Mooney-Rivlin formula on describing the mechanics properties of rubber-like material. It is more precise to use Three Ogden formula in nonlinear finite element calculation, which provides a good reference for the design and calculation of gate water seal structure.
