An aircraft rudder surface drive actuator performance test device

Abstract

The invention relates to an iron bird bench test system, in particular to a performance testing device of an airplane steering surface drive actuator. The device comprises a bracket, the steering surface drive actuator (5), a steering surface imitation part (6) and a loading actuator (7); the steering surface imitation part (6) comprises rocker arms (6-1 and 6-3), mass plates (6-2) and a rotary shaft (6-4); the rocker arms (6-1 and 6-3) are fixedly connected with the rotary shaft (6-4); the mass plates (6-2) are symmetrically fixed to the two ends of the rotary shaft (6-4); one end of the steering surface drive actuator (5) is fixed through the bracket; the other end of the steering surface drive actuator (5) is connected with the steering surface imitation part (6) through the rocker arm (6-1); one end of the loading actuator (7) is fixed through the bracket; and the other end of the loading actuator (7) is connected with the steering surface imitation part (6) through the rocker arm (6-3). By means of the performance testing device of the airplane steering surface drive actuator, the problems that in traditional design, a loading system is not convenient to install, output force of an airborne actuator is difficult to measure, the stiffness analog is dispersed and accuracy is low are solved, and optimal design of the iron bird bench actuator and a back end system is achieved.

Description

technical field [0001] The invention relates to an iron bird bench test system, in particular to a performance test device for an aircraft rudder surface driving actuator. Background technique [0002] In the development process of the Iron Bird, the design and construction of the actuator and the back-end system often become the main technical difficulties in the development of the Iron Bird. The design of the actuator and the back-end system includes stiffness simulation, space layout of rudder surface simulation parts, loading system and other mechanisms, simulation of key parameters, etc. The load bearing of the bench is also one of the key technical points that must be considered. [0003] At present, the design of the domestic iron bird stand is nothing more than the following states, usually the trailing edge of the wing is a rigid stand, the front and rear fulcrums of the airborne actuator are installed with real airborne supports, and the rudder surface is also made...
