Variation Rules of Warping Effect with Respect to Parameters of Cylindrical Helical Spring

摘要

The effect of warping deformation on the natural frequencies of the cylindrical helical spring with non-circle cross section,based on naturally curved and twisted beam theory,is analytically investigated in this paper.The purpose of this article is to discuss the variation rules of the warping effect with respect to the parameters of springs.The numerical simulations show that the results of the present model demonstrate a good agreement with those of ANSYS when the warping effect is included.Additionally,the effect of warping on the natural frequencies is more obvious as the parameters of the spring increase.
