摘要
本文在精确的非均匀BSI梁自由振动理论中(即考虑剪切变形和转动惯量的影响),略去某些次要因素,给出了仅以梁挠度W为变元的近似微分方程,从而便于数值求解BSI粱的固有频率和振型。
This paper neglect some secondary factors in the exact theory for the free vibration of nonuniform BSI's beam(ie including the effects of shear deformation and of rotatory inertia), resulting in an approxmation differential equation with one dependent variable by beam deflection W. It is convenience to obtain the natural frequency and mode of vibration of BSI's beam with some numerical methods.
