介绍了国外在伺服气动弹性力学方面的某些新成就:改进了非定常空气动力的最小状态法,它能提供精确、低阶伺服气动弹性模型;开发了以匹配滤波理论和随机过程理论为基础的若干分析方法,这些方法能有效和直接地计算临界阵风分布形式和随时间变化的阵风载荷。此外,概述了旨在改善设计方法的两个研究计划:一是结构/控制系统一体化设计方法;二是为低阶鲁棒数字控制率的气动弹性应用研究准备某些实用方法。最后,简述了主动柔性翼设计的现状。
Some new achievements abroad in the field of servo aeroelastic mechanics are introduced: the unscheduled aerodynamic minimum state method is improved, which can provide accurate and low-order servo aeroelastic models, and a new method based on matched filtering theory and stochastic process theory is developed Several methods of analysis are available that can efficiently and directly calculate the critical gust distribution and the gust load over time. In addition, two research plans to improve the design method are summarized: one is the integrated design method of structure / control system; the other is to prepare some practical methods for the study of aeroelasticity of low-order robust numerical control rate. Finally, the status of active flexible wing design is briefly described.
