  • 简介:一个模拟模型一电子地控制了二个螺线管阀门燃料注射系统因为一台柴油机引擎在AMESim环境被建立。模型的精确性与试验性的数据通过比较被验证。在不同控制模式下面的主要注射的数量上的注射前控制参数的影响被分析。在喷洒控制阀门模式,主要注射的燃料数量逐渐地减少然后因为多注射居住时间的增加,到达稳定的水平。在针控制阀门模式,主要注射的燃料数量与升起的多注射居住时间增加;这效果在高速度的革命和大主要注射的脉搏宽度变得更明显。注射前脉搏宽度没在二个控制模式下面在主要注射的数量上有明显的影响;在主要注射的数量的变化在1mm3的范围。

  • 简介:高密度聚乙烯(HDPE)的薄墙样品经由注射塑造,不同注射速度从100mm/s到1200mm/s被准备。在张力的力量和幼仔模量的重要减少与增加注射速度被观察。为了在这后面调查机制,减少,取向,分子的重量,分子的重量分发,融化流动率,crystallinity和水晶HDPE的形态学用二维的宽角度的X光检查衍射(2D-WAXD)被描绘,胶化浸透层析(GPC),毛状的电流测定和微分扫描热量测定(DSC)分别地。这被表明取向,分子的重量,分子的重量分发,融化流动率和crystallinity没与增加有明显的变化注射速度。不过,扩大的链晶体的内容或大合拢的链晶体被发现与增加注射速度减少。因此,在张力的性质的减少被扩大的链晶体或大合拢的链晶体的减少的内容主要贡献,这被结束。这研究为高速度注射塑造的申请向工业提供珍贵信息。
