飞行器舵面力矩模拟加载对整个飞行器的设计和定型有着重要意义。传统力矩加载方式多为轴对顶方式,应用场合受到较大限制。在吸取轴对顶加载方式经验的基础上,设计出一种利用铝型材搭建的专用翼面加载支架以实现飞行器的整机直接加载,具有快速装卸,轻便坚固的特点。在力矩加载过程中,舵机运动会对力矩指令的模拟跟踪造成额外影响,即产生了多余力矩。针对飞行器舵面加载的这种典型被动式特征,采用基于自测速形式的结构不变性原理方法抑制舵机自主运动过程中产生的多余力矩,并最终通过仿真和实物验证实现整个力矩加载系统的设计。
Aircraft rudder torque simulation load the entire aircraft design and shape is of great significance. Traditional torque loading methods are mostly axial-to-top, applications are subject to greater restrictions. Based on the experience of shaft-to-shaft loading, a special airfoil loading bracket using aluminum profile is designed to realize the direct loading of aircraft with fast loading and unloading, light and sturdy. During the moment loading, the steering motion has the additional effect of simulating the tracking of the torque command, ie generating excess torque. According to the typical passive characteristics of the aircraft rudder surface loading, the method of structure invariance based on self-test velocity is used to restrain the extra torque generated during the autonomous motion of the steering gear. Finally, the design of the whole torque loading system is simulated and verified by the physical verification.
