摘　　要：对于结构动力学方程,在分块增维精细积分法的基础上,使各个子块产生共同项,即子块相似化。这样精细积分每次循环的结果,多个子块可以同时利用,同时也减少了计算量和存储量。在非齐次项的处理问题上,取每个步长的中间值,简化了计算,也保留了精度。数值例题显示研究方法的高效性和可行性。The structure equations, based on Be block of increment dimensional precise integration method, so that each sub block into the common items, namely sub blocksimilarity. The precise integration of each cycle results, multiple sub blocks can beused at the same time, but also reduce the computation and storage. To deal with problems in nonhomogeneous term, intermediate values of each step, and simplifies the calculation, but also retains the accuracy. Numerical examples show the efficiency and feasibility of research methods.
