摘　　要：针对现有的锚固式密封垫截面设计法——工程经验和类比法相结合的方法缺乏具体理论支撑的问题,采用ABAQUS有限元软件,建立了各锚固式密封垫截面在最不利的工况(错缝量为15 mm)下和正常工况(错缝量为0 mm)下的二维平面应变模型,研究了密封垫的截面参数(底部厚度、脚部尺寸、底孔高度和开孔形状)和材料性能参数(橡胶硬度)对锚固式密封垫防水性能的影响.结果表明:底部厚度和脚部尺寸对锚固式密封垫防水性能几乎没有影响;当中部开孔设置为拱形时,闭合压缩力较小,锚固式密封垫防水性能较高;底孔高度越大,最大接触应力和闭合压缩力越小,锚固式密封垫防水性能越差.To solve the problem of the lack of specific theoretical support for the current anchored sealing gasket section design method with relying on engineering experience and analogy,the ABAQUS finite element software was used to establish the two-dimensional plane strain models of various anchored sealing gasket sections under the most unfavorable condition with 15 mm staggered joint and the normal condition with 0 mm staggered joint.The effects of the gasket cross-section parameters of bottom thickness,foot size,bottom hole height and hole shape and the material parameter of rubber hardness on the waterproof performance of anchored sealing gaskets were investigated.The results show that the bottom thickness and foot size have slight impact on the waterproof performance of the anchored sealing gasket.When the central hole is set in arch shape,the gasket demonstrates superior waterproof performance with low closing compression force.As the height of bottom hole is increased,the waterproof performance of gasket is decreased,while the maximum contact stress and the closing compression force is also reduced.
