The dynamic equation of elastic linkage with compliance elements is derived for the first time and the validity of new balancing method is discussed.

首次推导出具有弹性元件的弹性连杆机构动力学方程，从理论上阐述了此平衡方法的有效性。

With the compliance changing rate method, the crack initiation time and the dynamic fracture toughness of CFRP and GFRP laminates were obtained at two kinds of strain rates separately.

利用柔度变化率方法确定起裂时间，分别得到在两种加载速率下CFRP、GFRP层板的动态断裂韧性。
