The Testing System of Precise Motion Transmission Chains Based on Virtual Instrument

Abstract

This paper mainly adopts the virtual instrument to realize the test on the accuracy of precise transmission chains, and a precise transmission testing system has been developed. The system based on the LABVIEW software can realize data acquisition, signal processing and display of results, meanwhile,it can dynamically analyze the precision of the transmission chain. The results of the actual measurements show that the testing system can accurately and rapidly measure the precision index, furthermore, it has the characteristics of high accuracy, good real-time performance, flexible operation, easy to modify the measurement program. the system can not only be used in signal measurement and analysis, but also can automatically record and store data. What is more, it can real-time display dynamic precision and transmission error curve of precise transmission chain , It is Suitable for the precision measurement and error analysis of high precision transmission chains (such as harmonic gears, planetary gears and so on) ,and has a good application value in this field.
