摘要
引用压杆屈曲函数构造两固端刚性拉索的一阶和二阶振型函数 ,由 RITZ法原理求得其相应的一阶和二阶固有振动频率。算例表明 ,RITZ法给出的显式解具有较好的精度 ,可方便地用于振动法测估刚性拉索的索力。
The buckling function of compressed bars was utilized to conceive a function that can describe the first and the second oscillation mode of fixed end rigid cables.By means of the RITZ method,the free frequencies of the first and the second mode of the cables were given.The example shows that the RITZ solution is accurate enough and it can be used conveniently to measure and estimate the tension of rigid cables with vibration method.
