摘要
计算结果表明,用一般的振型叠加法计算无质量处的位移是不正确的。为了解决这个问题,本文给出修正的振型叠加法.用该方法计算的结果完全符合问题的精确解。本文还给出了该方法的严格理论证明。
Results of analysis reveal that the solution for the displacement at zero-mass point by using the conventional method of mode-superposition is not correct. In order to solve the problem, this paper presents the modified method of mode-superposition, by which we can reach the accurate solution. Furthermore, the strict theoretical testification of the modified mothod is given in this paper.
