用于大机动飞行仿真的宽频带高速三轴转台

A Three-Axis Table wrth Wide Frequency Band and High Speed for Simulation of Highly Maneuverable Flight

为满足一种新型大机动飞行器飞行姿态半物理仿真的要求,采用变增益液压伺服机构和变系数前馈补偿器等技术,对某三轴液压飞行仿真转台进行了改型研制。在转台具有良好低速特性的同时,其大振幅下的频宽和高速响应特性达到了国际同类转台的水平。所研究实施的技术方案,对研制新转台及旧有转台的技术改造都有参考价值。

The techniques on variable-gain hydraulic servomechanisms and variable-coefficient feedforward compensators have been used for an operational development of a certain three-axis hydraulic flight simulation table to satisfy demands of semi-physical simulation of flight attitudes of a new aircraft with high maneuverability. With a good low speed performance ,this table achieves world standards of the same kind of tables in the fields of high speed response and frequancy band width on large amplitude. The technical measures adopted in this table would be of reference values in developing new tables and improving old ones.
