However, the digital randomvibration control systems currently based on power spectrum fitting can only generate randomvibration exciting signals with Gaussian probability distribution.
然而，目前基于功率谱均衡的数字式随机振动控制系统只能产生高斯分布的随机振动激励信号。

To enhance the reality of vibration simulation testing and the effectiveness of vibration stimulation testing, it is necessary to generate true random drive signals with super-Gaussian distribution.
