摘要
本文提出多自由度振动系统固有频率的一种近似解法。应用此法估算基频,在假设振型非常粗糙的情况下,仍能有较高的精度,同时亦能给出精确值的范围。
A new approximate solution is given in this paper to estimate the fundamental frequency of vibration system with multiple freedom degree.Adoptimg this method,a high accuracy can be gotten even with a rough hypothetic.The results can also give the range of the exact solution.
