合格性试验

Taken example for solving real engineering problem, the methods and steps for the analysis of the steering-wheel vibration is discussed.

为了解决某型轿车的转向盘振动问题，本文通过对影响转向盘振动的诸多因素逐一进行分析，结合先进的试验手段和CAE分析技术，找出了引发该轿车转向盘振动的主要原因是车轮动平衡质量不合格及固定转向柱管的仪表板横梁刚度不足，通过提高车轮动平衡质量，改进仪表板横梁设计，提高仪表板横梁的刚度和固有振动频率，结合道路试验进行主观评价，改进后的转向盘振动达到了平顺性要求。

Result shows that the pouring techniques of concrete have little influences on workability, slump, spread, surface crack and temperature control, but more on laitance.

结果表明，混凝土浇注工艺对和易性、坍落度、扩展度、表面裂缝、温度控制影响较小，对浮浆的影响较大；均匀振捣与超振剪力墙的浮浆厚度较大，抽芯试样强度合格，未振捣的剪力墙的浮浆厚度较小，但抽芯试样强度不合格；每层浇筑厚度宜控制在0.8～1m，且均匀布料振捣，该值能为现行规程的修订与完善提供试验数据参考。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
