本文讨论了基于最小势能原理的里兹法的收敛性。
The convergence of Ritz method based on the principle of minimum potential energy is discussed.
然后根据里兹法,得到结构精确综合的频域运动方程与频响函数;
The exact synthesis equation of motion in frequency domain and frequency-response functions for structural vibration were obtained according to the Ritz procedure.
伽辽金法计算结果比里兹法计算结果略小,整体变化趋势基本相同。
The result of Rize method is on the small side than Galerkin method, but whole variant trend is identical.
