| 摘 要： | 分析了圆柱、柱锥形及回形纳米碳管弹簧在轴向载荷作用下的变形，给出了它们轴向刚
度$K_{\rm p}$的统一表达式. 为验证$K_{\rm p}$公式的有效性，还将圆柱形碳管纳米弹簧$K_{\rm p}$
的理论解和相应的试验结果、有限元结果进行了比较. 结果发现，碳管纳米弹簧的$K_{\rm p}$
理论解和试验结果、有限元结果均较为接近.

| Abstract: | By the classical method of strength of material, the
deformation of carbon-tube nanosprings (CTNS), including cylindrical, conical
and looped ones, under axial-compression, is analyzed, and a general
formula for stiffness of CTNSs is obtained. In order to validate the
formula, the stiffness for a cylindrical CTNS is calculated and
compared with the corresponding experimental and FE
(Finite element) results. It is shown that the present value of
the stiffness is very close to both experimental and FE ones. |
