中文摘要：
介绍了独立分量分析的基本原理和算法步骤,运用其对齿轮箱实测的瞬态声音信号进行了降噪处理,然后运用阶次倒谱技术分析了降噪后的信号,找到了故障特征,成功地判别出了齿轮箱的轴承外圈故障,验证了该方法的可行性和有效性。
英文摘要：
The principle and algorithm of ICA is presented,and then through the analysis of transient acoustic signals on gearbox combined with order cepstrum analysis,the gear fault characters are found,showing its feasibility and validity.
