摘要
设计、制造并标定了大型力锤，克服了信噪比不高的缺点，使瞬态激振成功应用于水电机组的实验分析，并取得了较高的试验精度．
A large exciting-hammer has been designed,made and calibrated. Due to the elimination of the shortcming of poor S/N ratio,the transient-exciting-method has been used in experimental analysis of the hydraulic electro-generating set successfully and good precision of experiments has been obtained also.
