【摘要】 利用INV智能信号采集处理分析系统取代传统记忆示波器频度法进行环境振动测量,为精密仪器使用环境的振动指标进行科学、准确的评估。该分析系统采用时域、频域结合的分析方法,采样、示波同步进行,能够对现场的异常情况进行实时监控和处理,并且随时可以对伺服拾振器的输出信号进行多种分析处理,完成数据统计。这种环境振动测量方法,实用、高效,具有一定的应用价值。更多还原

【Abstract】 The DASP system is applied in the measurement of environmental vibration,instead of the oscilloscope conventionally used,which leads to the convincing evaluation of the spot for accurate instruments.As an implementation of time domain and frequency domain methods,this system performs data acquisition and waveform display at the same time,which makes possible the real time monitoring of the on-site measurement and corresponding actions if necessary.In addition,the output signal from the servo-transducer can be analyzed by various methods.The DASP system is therefore recommended in the similar applications.更多还原
