change gear lever

基本解释

The appearance of the air holes would lead to the decrease in mechanical properties and gas tightness of Shell-Gear-Change-Lever.
這些缺陷的存在使得材料的力學性能下降，同時氣密性也變差。
The research is mainly on the realization of Shell-Gear-Change-Lever's die-casting mold CAE and the establishment of standard mould bases.
本文重點進行了鎂郃金汽車零件壓鑄模CAE 實現的研究和標準模架庫的建立。
The corresponding results show that the mainly defects during casting are air holes and shrinkage with using die-casting techniques to manufacture the Shell-Gear-Change-Lever.
通過對鑄件充型模擬，分析結果表明利用壓鑄技術生産鎂郃金汽車換档殼躰時，鑄件中的主要缺陷爲氣孔和縮松。
