摘　　要：元胞单元法是一种新的力学计算方法,它将结构的整体求解变成局域分析,通过力的局域间的不平衡传递达到最终的整体平衡。它对计算机容量要求极低,在大型复杂结构的计算方面具有良好的前景。同时,由于借用了元胞自动机的思想,可形成一种高度并行的算法,适用于未来并行机的要求,是一种富有发展潜力的新的数值方法。将该方法应用于卷板机花键的静力分析,以检验其实际应用的可行性。文中以直观的方式介绍了元胞单元法的基本原理,给出了详细的计算步骤和结果,探讨了方法的有效性,并对其优点和存在的问题进行了讨论。Cellular element method is a new numerical method. In this method the global analysis of structure is changed into a series of local analyses by using the idea of Cellular Automata. It may have a promising future for large structures because it hardly has any special requirement on the capability of computer. It can be developed into a highly parallel arithmetic to adapt to the request of parallel computer in the future. Therefore, the new method is a good numerical method with great potential. It is applied to the analysis of splines in this paper. The computing steps and results are presented. Based on the numerical results, the feasibility, advantages and disadvantages of cellular element method are discussed.
