[ 摘 要 ] 特种试验水池主要用于产品的各项试验，由于产品性能的复杂性和实验的多样性，对水池本身的强度、抗震、抗冲击提出了很高的要求。借助LS-DYNA软件可以模拟水池结构在受到产品冲击时的变化情况，从而定性研究水池结构在受冲击的过程中的数值变化，优化水池结构设计。反之，亦可得出产品在这个过程中的结构变化，对产品本身的结构设计有很好的借鉴作用。

[Abstract] Special experimental cistern is mainly used to carry out different kinds of experiment for products. The complex performance of products and the variety of experiments put heavy demands on the intensity and aseismatic property of the cistern itself as well as its performance against impact. The changes that the impact of products brings to the structure of the cistern can be simulated with the help of LS-DYNA software in order to make clear the numerical changes. And consequently the device of the cistern can be optimized. Contrariwise, we can also get to know the structural changes of the products, which may help to improve the device of the products.
