| 摘 要： | 用傅里叶变换对含有噪声干扰的试验数据进行滤波，通常难以确定奇异点在空间的位置及分布情况。本文用小波变换对引信风洞试验数据进行滤波，通过选择合理的基小波、分解尺度和阈值对数据滤波后得到了引信涡轮角加速度的突变点，确定了引信击针脱离盲孔的时间，找出了某型引信早炸原因，解决了实际引信故障分析难题，保证了该引信的设计定型。

| Abstract: | It is difficult to confirm the position and distribution of singularities in space generally when the test data with noise disturbance is filtered by Fourier transform. This paper describes that test data of wind-tunnel is filtered by wavelet transform. By choosing rational base wavelet, level and threshold, the saltation of angle acceleration of fuze turbine was obtained, the time when a stab firing device of fuze is divorced from a hole was assured, it is important to analyze the motion law of fuze. By finding out the reason of the fuze early burst, the design was guaranteed. |
