摘要 针对汽车转向盘角脉冲输入场地试验数据的特点,对实际数据处理中遇到的问题进行分析,对比了采用FFT方法和时域分析方法进行数据处理的结果,并详细分析了FFT方法在实际数据处理中存在上述问题时,数据处理精度不高的原因。 Aiming at the features of field test with steering wheel angle pulse input,the problems encountered in data processing are analyzed. The results of data processing by using FFT and time domain analysis two methods are compared,and the reasons for inadequate accuracy using FFT scheme in data processing when abovementioned problems happen are analyzed in detail.
