[Abstract]:Based on the dynamic measurement method and the high precision circular grating as the sensor, a set of dynamic measuring system of gear transmission error is constructed in this paper. This paper focuses on the research of signal processing, including denoising, frequency domain analysis and blind signal processing, and applies these methods to the processing of transmission error signals. Then the method of calculating some gear error data from the transmission error curve is given. Finally, the transmission error of the servo mechanism is tested, and the test data are analyzed and calculated. The main contents of this paper are as follows: 1. The measuring method of transmission error is studied. Based on the dynamic measurement method, the transmission error is tested. Because the high resolution data acquisition card is used in the test system, the direct counting measurement method is used in the counting measurement method. 2. According to the characteristics of seeker servo mechanism, the whole scheme of transmission error testing system is designed. In the hardware part, the functions of the selected hardware are introduced, including angle encoder, data acquisition card, multi-axis motion control card and driver. In the software part, using LabVIEW as the software development tool and adopting the modular programming idea, the functions of initialization setting, data acquisition, data storage, data analysis, data display and report printing are realized respectively. 3. The traditional filter denoising method and wavelet de-noising method are studied, and the traditional filter denoising method is applied to the analysis of transmission error. The analysis results show that this method can effectively filter the noise in the signal. It has good practical effect. After filtering, the transmission error curve is analyzed in frequency domain, and the accuracy of frequency conversion and tooth frequency information is observed by spectrum diagram. 4. In order to obtain the transmission error of a single gear, the blind source separation theory is deeply studied, and the theory is applied to the separation of the transmission error curve of the gear pair. After the transmission error of a single gear is separated, the transmission error curve is analyzed and calculated according to the theory of gear error analysis, and the single error data of the gear is obtained. The whole system is combined with software and hardware, and the collected data are analyzed and processed, and the measured results are obtained.
