航空工业部六二三研究所已研制成SKD-1型随机振动控制系统。SKD-1系统以国产622型小型数字计算机为控制机,配A/D、D/A等实时控制设备,研制了一套随机振动控制软件,可以实现各种谱图的真随机振动,并在振动控制的同时对试件各测量点进行联机测量分析,分析功能有自谱、互谱、自相关、互相关、传递函数和相干函数等常用的功能。用该系统也可作磁带记录的振动信号的分析处理。分析结果可用打印机、X-Y记录仪和穿孔机输出。该系统能满足一般工业产品的随机振动试验标准的要求,价格比进口的系统便宜,宜于
The 633 Institute of Aviation Industry has developed SKD-1 random vibration control system. SKD-1 system with domestic small 622 digital computer as the control machine, with A / D, D / A and other real-time control equipment, developed a set of random vibration control software, you can achieve a variety of spectra of true random vibration, and in Vibration control at the same time on the measurement points of the specimen on-line measurement and analysis, analysis of self-spectrum, cross-spectrum, autocorrelation, cross-correlation, transfer functions and coherence functions and other commonly used functions. The system can also be used for magnetic tape vibration signal analysis and processing. Analysis results can be used printers, X-Y recorders and punch output. The system can meet the requirements of random vibration test standard of general industrial products, the price cheaper than the imported system, suitable
