Abstract

With the development of China's aerospace industry, the demand for long life and high reliability electrical transmission of space conductive slip rings is increasing. This article takes the bundle brush conductive slip ring as the research object, based on fractal theory and wear model, modifies fractal parameters, and establishes a prediction model for slip ring wear. The influence of fractal parameters and load on wear in the model was analyzed through numerical calculations. The average relative error between the predicted model results and experimental data during the entire wear process was 0.28. The wear prediction model established in this article can better reflect the actual wear process compared to other models, and can to some extent guide the optimization of sliding ring design parameters.
