摘要
本文应用加权残数法导出了考虑剪切变形、转动惯量及弹性地基等因素的变截面梁的自由振动方程。并由一简例说明本文推导方法的精度。
A Mathod of Weight Residuals (MWR), applied to solve a free vibration equation of variable cross section beam is presented,considering all the intluential factors: detrusion, rotary inertia and elastic fondation etc. A simple numeical example is given to verify the accuracy of the MWR.
