摘要
本文用有限元法研究了在小应变中转动几何非线性情况下粘弹性材料梁的动响应问题,对粘弹性几何非线性梁的研究表明,在适当考虑梁的几何非线性性质的情况下,粘弹性阻尼梁具有更好的减振效果.
In the paper,the element which takes account of the effect of transverse shear deformation is used,and the geometic nonlinearity of moderate rotation is guarenteed. The dynamic response of beam under the visco-elastic damping is discussed.the results show that the effect of reducing vibration will be improved,if geometric nonlinearity is guarenteed.
