As the critical equipment which provides transmission in the steering engineer of aerospace craft, the double-input aerospace servo reducer in this paper achieves the double-input function in the aerospace field and consequently solves the problem that the craft will lose power when its only power resource has been damaged. And it also has the high precision, high rotational speed,low mass and low size. Aimed at verifying all the performances of the reducer and identifying the reasons, this paper designs its test-bed which can accomplish the transmission efficiency, transmission accuracy and torsional stiffness experiments.The main performances of the double-input aerospace servo reducer are first analyzed in the article, which include the transmission efficiency, transmission accuracy, torsional stiffness and so on. Then, the test principles and methods about all the performances are presented and the key formula deduced.According to these test principles and test methods, the overall structure of the transmission efficiency, transmission accuracy and torsional stiffness test-bed are designed, and then the key parts and installations of the test-beds are introducedThe control part of the transmission test-bed is developed in accordance with structure and all the control instruments are researched and designed. On basis of the LabVIEW platform and the analysis of the transducer, the acquisition system which can achieve the test is developed.Finally, the various performance tests of the reducer are done on the test-bed and the function of the test-bed is verified consequently. And the function of the reducer is analyzed in the same time. |
