Thus, the complete scaling law is invalid, established by the traditional similitude analysis, reducing the prediction accuracy. To weaken the distortion effect, a chain separate similitude analysis method is presented to establish the distortion scaling law, thereby enhancing the prediction accuracy. First, a global scaling law is obtained based on dimensional analysis. Second, distortion model is formed by introduced a distortion coefficient, which allows for the global scaling law to be chain-separated into complete and partial similitude scales. Third, two sub-models of complete similitude and partial similitude are constructed respectively to weaken the distortion effect. Then, the scaling laws are established including complete and partial similitude, respectively. On this basis, the natural frequency distortion scaling law is derived. Finally, finite element models of the concentrator unit prototype and distortion model are developed to validate the suggested method. Through simulation analysis, the large-scale prototype first-order natural frequency predicted value is 28.34 Hz, while the theoretical value is 28.32 Hz. The prediction error of the first four orders’ natural frequency for the prototype is kept within 0.4%.

This study is based on the space station experimental cabin’s on-orbit technology testing platform, and it systematically investigates the wear debris migration behavior of the brush–slip ring mechanism. Through long-term on-orbit testing observations, a three-dimensional multiphysics coupling model was developed using a Monte Carlo-Finite Element joint algorithm. This model reveals the migration mechanism of wear debris under the combined effect of the electrostatic field and electron radiation field: debris without initial velocity primarily adheres to the metal ring surface; debris with initial velocity migrates towards the shield with a speed of up to 0.0136 m/s in the electrostatic field, while a small amount adheres to the side of the insulating baffle due to electric field distortion near the brush; under the electron radiation combined field, the surface potential reconstruction of the dielectric increases the local field strength to 2.2 × 10<sup>8</sup> V/m, significantly enhancing the migration trend of the debris towards the insulating baffle and causing the debris on the inner side of the shield to detach and impact the baffle. The study accurately reproduced the spatial distribution characteristics of the wear debris and revealed the discharge behavior induced by the debris through trajectory prediction models and comparison with on-orbit experimental data.
