钻井液振动筛动态特性分析及动态强度校核

The Dynamic Property Analysis and Strength Calculation for Shale Shaker

用Pro/MECHANICA软件对SDZS钻井液振动筛筛箱的动态特性作分析研究,获得了筛箱低阶固有频率与模态振型,找出了筛箱在额定载荷作用下各部位的动态应力分布规律,并对筛箱的动态强度进行了校核。分析结果表明,筛箱的结构设计合理,且在设计工况下,动态强度满足要求。所获筛箱低阶固有频率与模态振型,为该筛的改进设计及后续筛箱动态强度的试验研究提供必要的依据。

The dynamic properties of the model SDZS shale shaker are obtained using the software Pro/MECHANICA. The natural frequencies and mode shapes of the screen are calculated, and the distribution law of dynamic stress is found out. It shows that the structure design of the screen is reasonable. Under the working conditions designed, its dynamic strength is satisfied. The calculating results will be of significance to the design improvement, and will be helpful for the experiment research of dynamic strength.
