| 摘 要： | 闸板胶心是闸板防喷器封井的关键元件。胶心抱紧力是衡量闸板胶心能否可靠封井的重要参数。根据闸板防喷器工作性能要求,通过建立闸板总咸力学模型,应用橡胶非线性大变形理论,导出了闸板胶心抱紧力计算式,并编制了计算机程序。

| Abstract: | The ram rubber is a key part of a ram-type blowout preventer and its homing force is an important factor of the reliability service of the preventer. The formula for calculating the holding force of ram rubber is derived by establishing the mechanical model of the ram assembly and applying the non-linear large-deformation theory of rubber, and then a computer program is worked out. |
