随机数据的全部分析工作均由7330部分析组完成。试验人员把随机输入和响应数据记录在磁带上,供分析组使用。试验人员充分了解分析设备的能力和限制是很重要的,这样才能正确地分析试验要求和正确地解释数据。尽管详尽描述随机振动的参数已在第三章讲过了,但下面要讨论的不是理论情况,而是实际数据分析设备的能力、 All the analysis of random data by 7330 analysis group completed. The experimenter recorded random input and response data on tape for use by the analysis team. It is important that testers fully understand the capabilities and limitations of the analytical equipment in order to properly analyze the test requirements and interpret the data correctly. Although a detailed description of the parameters of random vibration is given in Chapter 3, what is discussed below is not the theoretical situation, but rather the ability of the actual data analysis equipment,
