In addition, it is also a perplexed engineering problem in designing the under-structural column of ACSR when considering the supporting stiffness to the top of the column. 另外，在設計波紋拱下部結構柱時(shí)，如何考慮波紋拱對柱頂支承剛度也是困擾工程界的一個(gè)問(wèn)題。
By changing these parameters and the Z-directional stiffness of the outer-ring, the stiffness and the damping characteristic of the damper can be varied. 在轉子系統支承中引入摩擦阻尼器能夠降低支承剛度，從而降低系統的臨界轉速，避開(kāi)工作轉速。
