研究了流体噪声的湍流传递行为及信号源的性质对相关测速系统的影响,分析了相关测速系统误差,并提出了理论修正该误差的方法,使得相关测速成为一种绝对的测量方法。在理论分析基础上进行了实验研究,理论和实践得到了较好的统一。
The influence of the turbulent transmission of fluid noise and the nature of the signal source on the relevant speed measurement system is studied. The error of the related speed measurement system is analyzed. A method to correct the error is proposed, which makes the relative speed measurement an absolute measurement method. Based on the theoretical analysis, experiments are carried out, and the theory and practice are well unified.
