The combination of short time spectrum analysis, extraction and iteration has a high estimation precision and a little amount of computation.
该方法通过短时谱分析与抽取叠代相结合，提高了估计精度，减少了运算量。
The spectrum of short time signal and part signal can be detected from vehicle vibrational signal which is difficult to be detected by common analysis method.
把路面激励信号从车辆整体振动中分离出来；同时从频域把短时或局部信号的谱检测出来，实现了常规分析方法所不能达到的功能。
