| 摘 要： | 对相对电磁激振器利用三角形脉冲信号进行机床瞬态激振的一些问题进行了探索和研究．结果表明，这种激振方法克服了目前国内广泛应用的手锤激励法试验和信号处理的不足，并同随机激振，正弦激振做了对比，测试分析结果比较理想．

| Abstract: | Some problems about the use of triangular impulsive signals on relativeelectric-magnetic exciter to perform transient excitation for machine tools are explored andstudied. The results show this method can cover the shortage of signal treatment in hand-hammer exciting tester.It is also seen that the results of measuring analysis are rather idealin comparison with the random excitation and sine excitation. |
