Abstract

The invention discloses a main wheel turning ground control torque measuring device and method. The device comprises a supporting base on which a torque sensor is vertically installed. A ground simulation platform is horizontally installed on the top of the supporting base through a slewing bearing. The torque sensor is connected with the ground simulation platform through a torque pin. The supporting base is fixedly connected with the inner ring of the slewing bearing, and the ground simulation platform is fixedly connected with the outer ring of the slewing bearing, so that the ground simulation platform can slew relative to the supporting base. The torque sensor is prevented from being influenced by a vertical load, and moreover, the torsional moment under the condition of coupling of various influence factors such as different load distributions, tire pressures and tire-ground relative friction forces can be directly and accurately measured by the torque sensor, the limitation of torque measurement of the force sensor is solved, and the influence of additional factors such as transmission and friction loss on the test result is reduced.

Description

Technical field [0001] The invention relates to a frame type main landing gear test, in particular to a device and method for measuring the turning ground control moment of the main wheel of the frame type main landing gear. Background technique [0002] When the frame-type main landing gear is turning, in order to improve the turning efficiency and reduce the turning radius, the last pair of main wheels needs to be turned. However, due to the load distribution of the whole machine, the load distribution of flat tires, the tire pressure and the ground- Many factors such as the relative friction of tires have a great influence on the turning control moment. Therefore, it is necessary to test whether the main wheel turning control mechanism can satisfy the frame-type main landing gear to provide fast and effective turning moment when the aircraft is turning. Such products are an important indicator of aircraft functional performance. [0003] In the previous turning moment measureme...
