Comprehensive testing device and method for rudder pedal force and angle in control cabin

Abstract

The invention provides a testing device and a corresponding testing method for rudder pedal force and angle in a control cabin. The testing device comprises a testing fixture body which is installed at the upper part of a rudder pedal stand column. The testing fixture body comprises a first installation part which is used for installing a pedal force measurement instrument and a second installation part which is used for installing a pedal angle measurement instrument. The testing device additionally comprises a pedal, which is fixedly connected with the pedal force measurement instrument. By adopting a concept of integrated and modularized design and using one single fixture to integrate two different testing modules, the simultaneous accurate testing of rudder pedal force and angle data is realized; and compared with the traditional testing device and the traditional testing method, the testing device and the testing method provided by the invention can realize the synchronous measurement of force and angle parameters which cannot be realized by using general equipment, and is commonly suitable for the field practical situation of an assembly workshop.

Description

technical field [0001] The invention generally relates to the functional test field of the cockpit control mechanism of the aircraft flight control system, and in particular to a comprehensive test device and a test method for the rudder pedal force and angle of the cockpit. Background technique [0002] When the functional test of the cockpit control mechanism of the flight control system is carried out in the aircraft assembly workshop, the traditional measurement method is usually used: the control force and rotation angle of the cockpit rudder pedals are measured with general measuring equipment. This traditional measurement method has problems such as the interference of test parameters by human operation and large errors. In addition, because the use of general-purpose measurement equipment can only measure the steering force and rotation angle separately, and cannot be synchronized in real time, the relationship between force and angle cannot be obtained. Therefore, i...

Problems solved by technology

This traditional measurement method has problems such as the interference of test parameters by human operation and large errors. In addition, because the use of general-purpose measurement equipment can only measure the steering force and rotation angle separately, and cannot be synchronized in real time, the relationship between force and angle cannot be obtained. function, so it is difficult to achieve accurate acquisition of special measurement parameters such as rudder pedal activation force and maximum control force

The existing relatively accurate measurement method only uses the floor test bench on the iron bird testing machine, but this method has problems such as excessive volume and weight of the floor test bench and inconvenient installation, and is also not suitable for the actual situation in the assembly workshop.
