A method based on the application of an injection process analysis software is introduced in this article, which optimize injection process through changing the design of fuel - injection pump cam. a model of 1115 single cylinder direct injection diesel engine is used as an example. with the help of pre - journey optimization, increasing cam lift and using tangent - function can make the matching of the injection system with the diesel more reasonable. without changing fuel pump installing size, it can enhance injection rate and injection pressure and improve the diesel operating stability in low speed condition
本文以國產1115型單缸直噴柴油機為例，介紹一種應用噴油過程分析軟體改進噴油泵凸輪設計的方法，通過增大噴油泵凸輪升程、採用切線函數凸輪並優化預行程的方式，在不改變噴油泵安裝尺寸的前提下，可提高噴油壓力和噴油速率，改善柴油機低速工作穩定性，使噴油系統與柴油機匹配更合理。 -
As one of the most potential experimental stress measurement, ultrasonic technique was widely developed and applied in recent years. limited by their own characters, bulk wave and surface wave in ultrasonic frequency are difficult to be used to measure the internal tangent stress condition from the surface of medium. in many occasions, they will not be able to evaluate the working condition of mechanical components effectively
超聲波技術作為最有潛力的實驗應力測量技術之一，近年來得到了廣泛的發展和應用，然而超聲體波與表面波由於其自身的限制性，均無法從表面測量內部的切向應力狀況，在許多場合下無法有效進行機械構件工作狀態的評估。 -
If asphalt concrete specimen is in stabilization by exert confining stress before the static triaxial test, it is then found that under the condition that time is long enough, the volume of the specimen will shorten gradually and stable around a fixed value, and the amount of compression is essentially the half of the volume of void itself. it is also found that in stabilization by exert confining stress the linear phrase will be shorten in the figure of the static triaxial test of specimen, while the initial tangent modulus will be augment. 3
在進行靜三軸試驗以前先對瀝青混凝土試件進行圍壓穩定，發現在時間足夠長的條件下，試件的體積會逐漸縮小，並逐漸穩定在某一定值，其壓縮量基本上為其本身孔隙體積的一半；經圍壓穩定后的試件靜三軸試驗曲線上的線性階段明顯縮短，而初始切線模量增大。 -
