【摘要】 针对结构动力分析计算量大、耗时长的特点,在精细时程积分算法的基础上,设计了主-从结构动力响应的并行精细积分算法,采用C++语言开发了基于PC机群的并行计算程序,对4650个自由度,50个时间步的结构动力响应进行了并行计算,采用6台计算机计算并行加速比达到5.32,验证了程序的可靠性和高效性。更多还原

【Abstract】 Aim to the disadvantage of structural dynamical analysis huge computing capacity, long time consuming, this paper designed a master-slaver parallel structural dynamical response precision integration algorithm, based on the precision integration algorithm, then developed a program using C++ based on PC cluster system. For a large-scale structural dynamical problem with 4.650 degrees of freedom. 50 time steps, the parallel speeding-up was 5.32 with 6 CPUs. The results show than the parallel algorithm is robust and high efficient in PC cluster environment.更多还原
