普通钢材

笔者介绍了复合材料的性能，用大型结构分析软件ANSYS对玻璃钢复合材料制作的红绿灯架进行了有限元分析，并与普通钢材红绿灯架进行了分析和比较。

Compared with the plain steel , the property of glass fiber composite material is discussed , and a finite element analysis of the traffic light frame made of this composite material is conducted with ANSYS soft ware .

CFRP材料具有与普通钢材不同的物理力学特征，根据两种材料的物理力学性能差异，本文分析了CFRP拉索非线性静力性能、CFRP拉索系杆拱桥非线性静力性能和CFRP拉索系杆拱桥稳定与极限承载力。

The material properties of CFRP is different from steel . So the nonlinear mechanic behaviors and the load-carrying capacity of the long span arch bridge with CFRP or steel hangers and tie bar have been studied .

在该工艺条件下，渗金属速率比普通钢材提高10倍左右。

The rate of metal permeating has increased by about 10 times compared with the ordinary steels .

传统钢板剪力墙的内嵌板都采用普通钢材。

In the traditional steel plate shear wall system , the plain carbon steel is selected forthe infill panel .

这类钢材的售价每吨可以超过2000美元，是普通钢材的3倍。

Such steel can sell for more than $ 2000 a tonne , three times as much as standard grades .

结果表明使普通钢材表面显微硬度提高5～7倍。

The experimental result shows that the microhardness used new method is 5-7 times higher than that of former meterial .

您可以和他们联系吗？并咨询一下如果只用普通钢材配合高温涂料是否价格上还有得商量？

Could you contact them and let us know if you can get the price down by using regular steel with high temperature paint ?

中国钢铁产能过大，这从普通钢材的价格变化中就可看出。例如，本地热轧钢卷价格今年以来下跌了五分之一。

China has too much steel capacity . That is clear from the price movement of common steel products such as hot rolled coil , which is down a fifth in local terms this year .

高强度钢虽然相对普通钢材具有较高的强度但在冲压过程中会造成较大的弯曲回弹和扭曲变形，严重影响了冲压件的形状尺寸精度和后续装配及焊接的可靠性等。

However , the high strength sheet metal has larger springback and distortion than common rail train forming sheet , seriously affected the shape and size of stamping and welding assembly accuracy and reliability of follow-up and so on .

研究由形状记忆合金与普通钢材制成的硬夹心板的振动控制方法，求出硬夹心夹层板的平衡方程，并分析了变厚度智能夹心板的振动问题。

This paper proposed a control method for the vibration of the hard-sandwich plate made of shape memory alloys ( SMA ) and ordinary steel , obtained an equilibrium equation for the hard-sandwich plate , and analyzed the vibration of the smart changed hard-sandwich plate .

普通热轧钢材的合理洁净度及生产工艺探讨

Economical cleanliness and rational production technology for common hot rolled steel products

采用新一代钢铁材料超级钢代替原有的普通强度钢材制造中型客车或货车车轮，以此实现汽车减重、降低油耗和减少环境污染。

To implement the weight reduction , low fuel consumption and pollution control , the new-generation ultra-fine grain steel has been used to make automotive wheel spoke instead of common high-strength steel .
