The dishing ring seals belong the end face sealing parts , and act as sealing by some axial compression . because of different distribution of internal pressure and temperature , the friction inside the end - face is also different at all area 碟形密封圈属于端面密封元件，依靠一定的轴向压缩量进行密封，由于端面内压力分布、温度分布不均，端面内的摩擦状况也不是处处相同。
Three - dimensional model of t - branch tube compound bulging has been established by using advanced explicit finite element codes ansys / ls - dyna with the research of distribution law of equivalent stress and plastic strain 摘要采用显示动力分析软件ansys / ls - dyna建立复合胀形三维有限元模型，深入研究了三通管液压胀形过程中应力应变分布规律，系统比较了轴向压缩胀形和复合胀形过程中应力应变变化规律、胀形支管高度、壁厚分布的差异。
This article gives the subsistent ability and the analysis result of intensity after repair in the open field airplane composite material structure by research the intensity , rigid and repair problem under a axis compress loads on a typical three stiffened composite laminate which has a penetrability crack ( a scatter damage ) by a shrapnel 本文通过飞机典型复合材料三加筋层压板结构在被弹片划开一穿透性切口(离散源损伤)后，在轴向压缩载荷作用下所产生的强度、刚度以及修理问题展开了技术研究及探讨，给出军机复合材料加筋板在弹击后生存力以及外场修理后强度恢复分析结果。
The paper also discusses the applicability of the nanometer silica fume in the cemented soil as an additive . based on the analysis of micro - damage mechanism and damage performance of the cemented soil stabilized with nanometer silica fume , an elasto - plasticity damage model under uniaxial compression condition is established 最后，通过室内试验分析了纳米硅粉水泥土的细观损伤机制及其损伤特性，建立了无侧限轴向压缩条件下的弹塑性损伤模型，分析了损伤演化规律。
The calculator is placed in the core position in virtual instrument , the calculator software and the test systems combine more closely . the automobile clutch from move the dish total become two functions to experiment machine is gather the machine , electronics , calculator in the integral whole of the high performance test machine , its core constitute the part is a host and test system 轴向压缩特性测定中的压盘状态和拖曳分离特性测定中的压盘状态要求有很大的不同,压盘实现不同状态下的切换是双功能试验机必须具备的功能,论文提出了双功能压盘的设计方案。
