摘要
提出弹性体固有振动分析的一种解析方法 .以梁、板的横向振动为例说明该方法分析过程 ,求得固有频率 (方程 )与已有解析解一致 ,说明该方法有效 。
A analytical approach based on the Betty’s reciprocal theorem of work is introduced to study the natural vibration of continuous systems.As an example,the natural vibration analysis of beams and plates is given.From results one can find that the method is valid.It is more important that the approach is also applicable to more complicated cases.
