摘要
通过满足三支点静不定轴的边界条件来求解基本方程,得到多跨静不定轴的挠曲线方程,并应用能量法改进了计算公式,快速准确地求得三支点静不定轴的一阶临界转速。算例表明,这种计算方法精度能满足实际要求而计算量不大,计算方程简单,过程快速。
By using the boundary conditions of the statically indeterminate shaft with three fulcrums,the deflection curve square of the shaft is got;By utilizing the energy method to improve the calculation formula, the accurate first order critical speed of the statically indeterminate shaft with three fulcrums is obtained quickly. The illustration shows that this method is simple and quick,and the precision is satisfactory.
