摘　　要：针对某强迫风冷军用加固计算机声学噪声源、噪声特性及影响噪声的主要因素进行了实验研究。研究结果表明:影响强迫风冷军用加固计算机声学噪声特性的因素主要包括风机、机箱风道,同时也排除了风机罩对计算机声学噪声特性的影响,同时也提出了各主要影响因素对整机声学噪声贡献的占比,为将来进一步控制强迫风冷军用加固计算机声学噪声指明了方向。In this paper,the main acoustic noise source,noise characteristics and noise of a forced air cooling reggedized computer were stud-ied. Research results show that：the factors which effect acoustic noise characteristics of the forced air cooling reggedized computer include fans,chassis air channel,and also exclude the wind hood. This paper also puts forward acoustic noise contribution ratio of the main influencing factors. So this paper point out the direction for the further research of forced air cooling ruggedized computer acoustic noise control.
