采用有限元软件ABAQUS,分析活塞和活塞杆间Y形密封圈密封面上的接触压力和摩擦力。针对Y形密封圈存在的密封面接触压力过大和摩擦力波动较大的问题,在原来的Y形圈唇部增加一个O形密封圈,起静密封和提供弹力支撑的作用。分析结果表明,优化后Y形圈接触压力和摩擦力明显减小,且摩擦力曲线波动更小,既能保证密封效果,又减小了因摩擦过大引起的Y形圈磨损失效,提高了Y形圈的使用寿命。

媒介天然具有"放大"潜能。相对传统媒体而言,新媒体技术及其创生文化所构建的新媒体环境,更是成了社会风险前所未有的放大场域。一方面,新媒体与风险扩散之间形成了高度的技术耦合,新媒体技术在风险扩散速度、扩散范围、感知渠道、体验效果、不确定性等方面大幅提升了风险放大的概率、加剧了其放大后果;另一方面,新媒体技术创生的文化进一步驱动了风险放大中的信息传播机制与社会反应机制,导致风险的非理性放大以及相关社会运动的激化,使得风险又衍生出其他更多的社会风险。
