| 摘 要： | 本文通过对装载机及叉车的随机载荷分析，探讨了具有分段作业特点的非平稳随机载荷的制谱方法。结合装载机实测传动系载荷，提出利用“作业剖面图”制取“铲—续—铲谱”这一新的制谱的方法。该方法可推广应用于具有分段作业特点的其他工程机械载荷谱的制取。

| Abstract: | A method of preparing load spectrum of non-stationary random load with sectional operating characteristics has been studied by analyzing the random load in loader and ferk lift truck. Two new concepts of operating sectional drawing and shoveling by shoveling spectrum have been advanced for loaders. The method in this paper can also be used to prepare the load spectrum in other construction machinery with sectional operating characteristics. |
