基于赫兹接触理论，假设密封垫与筒夹连接器毂的接触为圆柱接触，建立了接触应力的数学模型。利用密封理论分别建立了预紧和工作状态下的密封力学模型，得到了预紧力、接触应力和密封宽度之间的关系。分析了结构参数与预紧力的关系，并通过有限元仿真和实验进行了验证。设计了一个实验系统，并进行了实验，以验证分析模型。有限元模拟结果与实验结果吻合较好，预紧力和密封宽度的差异在可接受范围内。
The mathematical model of the contact stress is established based on the theory of Hertz contact with the assumption that the contact of a seal gasket and hubs of collet connectors is cylindrical. The mechanical models of the seal are established separately by sealing theory in the preloading and operating modes, and the relationships between the preload, the contact stress, and the sealing width are obtained. The relationships of structural parameters and the preload are analyzed and verified with finite element simulation and experiments. An experimental system has been designed and experiments have been conducted to verify the analytical models. Finite element simulation results and experimental results agree with analytical ones very well and the differences of the preload and sealing width are acceptable.
