摘要	Analysis and suppression of micro-vibration is an important concern in the research related to large space telescopes. In accordance with this concern, a series of works, including simulations and experiments, must be carried out to assess these micro-vibrations. Accurate disturbance data from the vibration source of a large space telescope serves as the basis for the required micro-vibration research; therefore, this paper describes the development of a novel generalized disturbance force measurement platform for large device vibration sources. Use of redundant piezoelectric sensors allows the structural stiffness and the measurement precision of the platform to be improved. The design of the mechanism, the simulation analysis and the calibration algorithms of the developed platform are analyzed theoretically. Based on the results of this analysis, a prototype system is designed and tested. The experimental results show that the dynamic relative error within the 8-800 Hz range is largely less than 5%, while the static relative error is less than 5%. The linearity of the generalized forces within a 40 kN range is within 0.1%FS, while the repeatability is within 0.1%FS. (C) 2019 Elsevier Ltd. All rights reserved.
