Using numerical simulation technology and method of orthogonal experiment design and single factor rotating optimization, this thesis makes a study of "lost core injection ", thus achieve the optimization of the parameters of molding process, to offer basic reference when developing production technology and mould of the plastics intake manifold. Based on the study of the status in quo and development trend of weight reduction on automobile, the application of plastics to automobile and intake manifold, then under the guidance of theory model and numerical simulation technology in the process of high polymer material, this thesis launches flowing main research work: First of all, on the basis of the three-dimensional model of the part and finite element net model, several designs of gating and running system are numerically simulated and analyzed via MPA of Moldflow.

本文在对当今汽车轻量化、零部件塑料化以及的汽车进气歧管塑料化的发展现状和发展趋势进行了研究和简要介绍，然后在高分子材料成型过程中的理论模型和数值计算方法的指导下，展开主要的研究工作：首先，在零件三维模型和有限元网格模型的基础上，使用Moldflow 的MPA模块对塑料进气歧管的多个浇注系统设计方案进行数值模拟，通过分析各个方案的充填质量、熔接线位置及数量等指标，得到了综合质量较高的4 个进料口的浇口位置及半限制型浇口大小的浇注系统。

Through the analysis and research,it was found out that the gate position of the runner system should be selected properly.

Results The total 100 frontal sinuses were all revealed. Of 100 ostia, nasofrontal ducts, ethmoid infundibula, and middle nasal meatuses, 4 didn't show up and 96 could be viewed with air channel and bone channel structures well demonstrated in 70, and the remaining 26 still showed their bone channel structures though their air channel structures were vanished.Conclusion The structures of the ostium of frontal sinus, nasofrontal duct, ethmoid infundibulum, middle nasal meatus, etc.

结果 50例被检查者的50个额窦全部显示；100个窦口、鼻额管、筛漏斗及中鼻道结构，4个未显示，96个被显示，其中70个窦口、鼻额管、筛漏斗及中鼻道的气道结构和骨结构均清晰可见，26个窦口、鼻额管、筛漏斗及中鼻道的气道结构消失但骨结构仍可见。

Methods:According to degree of stricture,14 patients were applied grooving incision,inferior semicircular removal and inferior semicircular removal plus grooving incision at 12 point of lithotomy position,respectively.

根据14例膀胱颈部挛缩的情况，分别采用膀胱颈口切沟术，膀胱颈口下半环切除术和膀胱颈口下半环切除加12点切沟术。

The deformation characteristics of the cross member pipe have been analyzed with determination of necking numbers and necking force.

分析了前横梁管材缩口的变形特点，确定了缩口次数和缩口力。

This item is a new type structure direct-acting overflow valve, which adopts dynamic pressure feedback principle. That is it adds a feedback cavity on common direct-acting overflow valve's core. When there is overfall on valve port, the hydraulic force of valve port will balance with feedback cavity's hydraulic force and spring force, so it can decrease spring's stiffness, just like adding a hydraulic spring, which works together with mechanical spring, so as to minish valve port pressure range.

本项目是一种新型结构的直动式溢流阀，采用动压反馈原理，在普通直动式溢流阀阀芯上增加一反馈腔，当阀口溢流时，阀口的液压力与反馈腔液压力和弹簧力相平衡，从而可以减小弹簧的刚度，等于增设了一根液压弹簧，使其和机械弹簧一起工作，以达到减小阀口压力变化范围的目的。
