不倒塔的实验探究

Experimental exploration of the tower without collapse

对圆盘对心堆叠而成的塔被敲击下端后的相关运动过程进行分析,将塔身的复杂运动分为3个阶段,采用控制变量的方法进行了大量实验.理论上通过堆塔原理来判断塔是否能够保持直立不倒,并对塔运动的全过程进行数值模拟,将实验结果和数值模拟结合,得到相关参量与塔稳定性之间的关系.

The movement process of the tower was analyzed when it was knocked on the bottom,which the tower was originally constructed with discs stacked against the center.The moving process of the tower was divided into three stages.The theoretical criterion of the collapse of the tower was given based on the called stacked tower principle,and the whole process was simulated numerically.Finally,the relationship between the relevant parameters and the stability of the tower was obtained comparing experimental and numerical simulation results.
