研究表明，齿轮运动信号分解能够有效检测齿轮的各类故障，高阶加速度信号对齿轮某些类型的早期故障更加敏感。
Experimental results show that gear vibration signal decomposition can detect different faults, and high-order acceleration signals are more sensitive to certain type of fault.
这就为齿轮的早期故障诊断带来了很大困难。
This brought great difficulties to diagnose the early fault of gear.
所以，如果能及时地发现齿轮传动系统的早期故障，对经济合理地安排维修设备时间，避免发生重大人身、设备伤亡事故有着十分重要的意义。
Therefore, it is important how to defect the fault of geared system as possible to make the repair schedule reasonably and economically and to avoid the body hurt and device damage.
