在分布式并行计算机环境下开展有限元并行算法研究是计算力学领域的前沿课题之一。基于区域分裂法，提出了结构动力分析两种形式的显式积分法的并行算法及步骤；同时，在用Ｔｒａｎｓｐｕｔｅｒ组成的分布式ＭＩＭＤ并行计算机上，采用３Ｌ并行Ｆｏｒｔｒａｎ编写了计算程序，并将其移植到串并行混合有限元分析软件ＰＦＥＭ中；最后，通过对三维空间钢架结构的实际分析，不仅验证了算法和程序设计的正确性，而且结果表明算法具有较高的并行效率。当２个和３个ＣＰＵ工作时，并行效率分别为０．８和０．７。
Finite element parallel algorithm research in distributed parallel computing environment is one of the frontier issues in computational mechanics. Based on the region splitting method, parallel algorithms and steps of explicit integral method of structural dynamics analysis are proposed. Meanwhile, on the distributed MIMD parallel computer with Transputer, a 3L parallel Fortran program is compiled and compared Finally, the actual analysis of the steel frame structure in three-dimensional space not only verifies the correctness of the algorithm and program design, but also shows that the algorithm has high parallel efficiency. When 2 and 3 CPUs work, the parallel efficiencies are 0.8 and 0.7, respectively.
