It also introduced selecting methods of the power redirectors in the steering-system design. Moreover it also did the further research on the power redirectors matching and coordination problem of the suspension system and the steering-system, calculated steering wheel strength and momental gradient when the heavy-duty vehicle matched two kind of power redirectors, did entire vehicle performance simulation research on two matching schemes of the suspension system and the steering-system.

還介紹了在轉(zhuǎn)向系統(tǒng)的設(shè)計(jì)過程中動(dòng)力轉(zhuǎn)向器的選型方法人人曰人人曰，另外還針對(duì)動(dòng)力轉(zhuǎn)向器匹配及轉(zhuǎn)向系統(tǒng)與懸架系統(tǒng)匹配問題做了進(jìn)一步的研究，對(duì)重型汽車匹配兩種動(dòng)力轉(zhuǎn)向器時(shí)車輛的轉(zhuǎn)向盤力和力矩梯度進(jìn)行了計(jì)算99riav.com，并對(duì)兩種轉(zhuǎn)向系統(tǒng)国产美女裸精品视频、懸架系統(tǒng)匹配方案進(jìn)行了整車性能的仿真研究。

In this article, three kinds of prealloy powder were developed by water atomization method. The base attribute, pattern, phase composition, differential thermal analysis of powder were researched. Sintered density, hardness, bend strength, Young's modulus were researched as hot pressed sintering temperature changing. By using abrasive wearing equipment upbuilt by the authors, the wear resistance were determined. Green-pressing density, simulated green-pressing strength and bonding momental of high frequency brazing were assayed. SEM corrosion structure and SEM appearance of fracture were observed.
