根据高水头闸门止水元件的工作特点,采用改进的门尼-里夫林模型进行非线性有限元仿真分析,并比较2种不同特性的止水元件在工作过程中的应力与变形规律以及粘弹性变化特点.仿真计算表明水封设计时选择硬度较小,适应变形能力较优且接触应力较大的止水元件能更有效地止水,计算成果为解决工程实际问题提供了科学合理的依据,并为类似工程设计提供了有益的参考. According to the working characteristics of high head sluice, the improved Mooney-Rivlin model is used to do the nonlinear finite element simulation analysis. The stress and deformation of two different kinds of sluice components are compared and the viscosity Elastic characteristics.The simulation results show that the design of the water seal has the advantage of less hardness, more suitable deformability and more contact stress, can stop the water more effectively and the calculation results provide a scientific and reasonable basis for solving the practical engineering problems , And provides a useful reference for similar engineering design.
