Torsion type aircraft control human sensing mechanism with adjustable starting torque and adjusting method

Abstract

The invention belongs to the technical field of airplane control human sensing system design and particularly relates to a torsion type airplane control human sensing mechanism with the adjustable starting torque and an adjusting method. At present, the torsion body type force sensing starting force is not easy to accurately adjust, the number of machined parts is large, a large number of materials are consumed, moreover, the size and the weight of the mechanism are increased, and starting force adjustment is complex. The mechanism is characterized in that a plurality of counterbores are formed in the circumferential direction of a first adjusting disc and the circumferential direction of a second adjusting disc, and the first adjusting disc and the second adjusting disc are respectively provided with a second arc protrusion and a third arc protrusion; the torsion body has torsion elasticity, and a plurality of threaded holes are formed on end faces of two sides of the torsion body; and a rotating shaft sequentially penetrates through the first adjusting disc, the torsion body, the second adjusting disc and an anchoring disc. The mechanism is advantaged in that by adjusting different installation angle positions of the first adjusting disc and the second adjusting disc on the torsion body, adjustment of the force sense starting force of the aircraft control torsion body is completed accurately, easily, conveniently and efficiently, the number of used parts is small, reliability is high, consumed materials are small, the size and weight of the mechanism are reduced, and costis reduced.

Description

technical field [0001] The invention belongs to the technical field of aircraft control human-sensing system design, and in particular relates to a torsion-type aircraft control human-sensing mechanism and an adjustment method with adjustable starting torque. Background technique [0002] The artificial sensory force system is set in the control system of the modern aircraft cockpit to provide control force simulation, so that the pilot can intuitively feel the state of the aircraft, and avoid the pilot's misoperation affecting the safety of the aircraft and the quality of flight control. The artificial sensory force system needs to have a centering function, so it is necessary to set a certain preload force, that is, the starting force, for the spring of the artificial sensory force system. When the pilot's control force on the control stick is greater than the starting force, the control signal is output. In order to ensure the accuracy of the starting force, it is necess...

Problems solved by technology

[0003] The purpose of the present invention is: aiming at the deficiencies in the adjustment of the force-sensing actuation force of the existing aircraft control twisting body type, a twisting-type aircraft control human-sensing mechanism and adjustment method with adjustable starting torque are proposed to solve the problem of the existing torsion body force. The actuation force is not easy to adjust accurately, it uses many parts, consumes a lot of materials, and increases the volume and weight of the mechanism, and the actuation force adjustment is relatively complicated, so as to improve the accuracy, operability and production of the actuation force adjustment of the aircraft control force sensing system Efficiency, reduced weight, volume and cost
