| 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。

| Abstract: | The buckling function of compressed bars was utilized to conceiv e a function that can describe the first and the second oscillation mode of fixe d-end rigid cables.By means of the RITZ method,the free frequencies of the firs t and the second mode of the cables were given.The example shows that the RITZ s olution is accurate enough and it can be used conveniently to measure and estima te the tension of rigid cables with vibration method. |
