Description
Technical Field
The invention belongs to the technical field of mechanical debugging, and particularly relates to steering rod measuring equipment of an airplane control system.
Background
The pilot operating device and the servo actuation system are subsystems of the flight control system. The free travel, auto trim function measurement of an aircraft is part of the commissioning of an aircraft steering system. The free travel measurement of the steering column of the airplane can check whether interference exists between the idle travel in the steering column control system and the middle of the steering column system, and the automatic trimming function debugging can check whether the on-off function is reliable during automatic driving. Both of these inspections are focused on the pilot steering system of the aircraft, an important inspection element in relation to the flight installation.
The free travel measurement current state checking condition of the airplane steering column is that an operator manually pushes the steering column. The inspection of the free travel requires that the external force is eliminated stably after a certain external force is applied to the steering column, so that the steering column is slowly returned to the middle under the pulling of the load mechanism, and the change position quantity of the measuring point on the steering column is measured after the return. The position quantity is extremely small and only a few millimeters, the positioning reference for placing the steel plate ruler in the seat cabin is extremely difficult to select, and the stable external force elimination is difficult to ensure that the steering column returns to the middle, so that the measurement has the problems of inaccurate single-frame repeated data and repeated work.
The automatic trimming function is debugged in the state checking condition, and the operator manually pushes the driving rod. The operator is required to push the steering column (the position change amount of the steering column measuring point is not more than 1mm in each displacement accuracy) at a slow speed, then the data on the telex computer is read, the steering column measuring point is required to be ensured to be within a required range, and the on-off state of the automatic balancing sensor is changed. When the on-off state of the automatic balancing sensor is changed, the position change quantity of the measuring point of the steering column is very small and only a few millimeters. Meanwhile, in order to ensure that data on a telex computer is read, when the on-off state of an automatic balancing sensor is changed, an operator needs to ensure that a driving rod is at the position for a period of time, and the measurement has extremely high requirements on the action of the operator. The measurement has the problems of inaccurate data and repeated work of single frame times.
In view of the foregoing, there is a need for a new steering column measurement device for an aircraft steering system that is accurate in measurement data, highly accurate, extremely simple to operate, and versatile for use with most aircraft models.
