摘要
介绍了在拟动力试验中两种位移控制模式下 ,下冲误差产生的机理 .以中央差分法为例研究了下冲误差在拟动力试验过程中的传播特性 。
In this paper, the development mechanisms of undershooting errors in two kinds of displacement-control modes of pseudodynamic test are introduced. Their propagation in pseudodynamic test is investigated with the central difference method as an example, and then discussions about the computed results are performed.
