摘要
对单自由度欠阻尼振动特性进行理论推导,得出其一般运动规律,并利用此规律对受电弓参数进行测定。对于框架归算质量的测量,考虑到其结构是一个复杂的空间杆件结构,测量比较困难,于是采用单频稳态正弦激振方法得到其归算质量。
The single-degree lack-of-damp vibration characteristics is derived theoretically and its general kinetic rule is educed. By this rule the pantograph parameters are measured. It is difficult to measure the equivalent mass of the frame,which is a complex dimensional spar structure. By the method of single frequency steady sine excitation,the equivalent mass of the frame is found.
