| 英文摘要 | In order to quantify dynamic forces/moments on the ground, a high-performance platform is necessary. This article improves the performance of the measurement platform from both structure and calibration. The plat-form's loading capacity and base frequency have been significantly increased by the introduction of an inno-vative load sharing ring, which also allows the platform to have other important and practical characteristics. Further improvements in platform performance are then achieved by optimizing the platform parameters using a multi-island genetic algorithm (MIGA). In addition, the calibration method is improved. The maximum relative error and cross-coupling error for the novel non-linear support-vector-regression-based (SVR) method are 3.42% and 6.54%, respectively, which are much superior than the 9.98% and 15.39% for the traditional linear least-squares-based (LS) calibration method, indicating better accuracy and decoupling performance of the SVR-based dynamic calibration. This has important implications for measuring dynamic forces and improving the stability of equipment in spacecraft. |
