冲孔的 meaning in Chinese
punched
Examples
- Thermal fe analysis can predict punch and die temperature distribution during the cooling process . holes drilled in the die allow for faster cooling
温度有限元分析可以预测冷却过程中冲床和模具温度的分布，模具中冲孔的冷却速度比较快。 - Because explosive shape is regular , steel plate mainly occurs shear damage similar to hole piercing , the extent of damage gradually increase with explosive mass increasing , finally explosion outcome will enter oilcan ' s interior from crevasse
由于药柱形状规则，钢板主要发生类似冲孔的剪切破坏，破坏程度随炸药质量的增加而加强，爆轰产物会从钢板破口处进入油罐内部。 - After the introduction of the innovations and the improvements of foreign hydraulic shock absorbers , the profound cushion mechanics study is done aiming to the shock absorbers chosen for the thesis ; the cushion process of hydraulic shock absorbers can be divided into several stages , which include local pressure loss caused by across sectional area shrinking , sharp edge throttling and aperture throttling
在对国外新型液压缓冲器的研究基础上，针对本课题所选液压缓冲器的结构特点，提出了分阶段建立机理数学模型方法。将液压缓冲器缓冲过程分为：由于流道断面突然收缩引起的局部压力损失阶段，缓冲柱塞的边缘和缓冲孔的边缘形成锐缘节流阶段，当缓冲柱塞进入缓冲孔中形成的缝隙节流阶段等三过程。
