摘要
本文通过对DN_2机车用喷油嘴针阀体的有限元数值分析,得出了针阀体在机械负荷、液力负荷和热负荷作用下的变形和应力分布的定量值.为喷油嘴设计研究、生产使用、提高喷油嘴工作可靠性提供了依据.
Under the effect of mechanical forces, liquid pressure and thormal load, the deformation and quantitative value of stress distribution of DN_2 Diesel Locomotive injection nozzle are obtained by finite element method. The results provide bases for the design, research, manufacture, utilization and the roliabieity improvement of the nozzle.
