随机振动数据处理有两种研究方法,一是应用电子仪器的仪器法,另一是应用电子计算机的数字技术。这两种方法互相补充、互相促进、并行发展。由于电子仪器价格昂贵,功能受到限制,本文研制一种随机振动数据处理的数字化方法。该法不但精度较高、速度快,而且可以扩大功能。因此本文应用数字法对随机振动数据进行全面分析、研究,并应用现代技术给出全部处理过程的快速、自动化方法。
There are two research methods for the processing of random vibration data. One is the instrumentation method using electronic instruments and the other is the digital technique using electronic computers. These two methods complement each other and promote each other and develop in parallel. Due to the expensive electronic equipment and limited functions, a digital method of random vibration data processing is developed in this paper. The law not only high accuracy, fast, and can expand the function. Therefore, this paper applies the digital method to conduct a comprehensive analysis and research on the random vibration data, and applies the modern technology to give a fast and automatic method for all the processing.
