论文摘要
我们研究了圆柱形物体由于横向振荡而沉入干燥的床时的行为。出乎意料的是，我们发现，在垂直底部底部水槽的各种横向摇动力范围内，而具有A'Foundation”的气缸，其中包括安装在其底部的秋季戒指，除了下沉以外的倾斜度。当应用足够强大的横向振动时，THELATTER情况似乎独立于基础的性质。磨损能够解释准2D数值模拟的观察到的行为，这也证明了入侵者的纵横比的影响。垂直的下水道动力学是在入侵者的牛顿运动方程的帮助下解释的。我们的发现可能会阐明地震期间建筑物和其他人造建筑的行为。
We study the behavior of cylindrical objects as they sink into a drygranular bed fluidized due to lateral oscillations. Somewhat unexpectedly, we have found that, within a large range of lateral shaking powers,cylinders with flat bottoms sink vertically, while those with a''foundation'' consisting in ashallow ring attached to their bottom, tilt besides sinking. Thelatter scenario seems to dominate independently from the nature ofthe foundation when strong enough lateral vibrations are applied. Weare able to explain the observed behavior by quasi-2D numericalsimulations, which also demonstrate the influence of the intruder's aspect ratio. The vertical sink dynamics is explained with the help of a Newtonian equation of motion for the intruder. Our findings may shed light on the behavior of buildings and other man-made constructions during earthquakes.
