Embodiment Construction

[0019] A specific embodiment of the present invention is: an arm adjustment control device, which includes a signal input module 1, a signal conversion module 2, a comparison voltage V1 module 3, a comparison voltage V2 module 4, a comparison circuit 5, and a display module 6 and control loop 8. Terminal 1 of the signal input module is connected to the control device, and terminal 8 of the control loop is connected to the control motor of the arm. The servo control current signal in the control device is connected to the signal input module 1, and the input current signal is converted into a variable voltage signal V by the resistor Ri in the signal conversion module 2. The comparator circuit 5 includes a comparator LM339 and six inverters (4069), and a valve voltage is provided at pin 7 and pin 4 of the comparator LM339 respectively, and as figure 1 Connect the comparison voltage V1 module 3 and the comparison voltage V2 module 4, adjust the Rc of the comparison voltage to c...

Abstract

The invention provides a force arm adjusting control device for an airplane structural strength test, and belongs to the technical field of strength test force arm control. The force arm adjusting control device comprises a signal input module, a signal conversion module, a comparison voltage V1 module, a comparison voltage V2 module, a comparison circuit, a display module and a control loop for controlling a force arm motor, wherein one end of the signal conversion module is connected with the signal input module, the other end of the signal conversion module is connected with the input end of the comparison circuit, the comparison voltage V1 module and the comparison voltage V2 module are connected with the input end of the comparison circuit, and the output end of the comparison circuitis connected with the display module and the control loop. The problem that a current force arm adjusting control device cannot be matched with a coordinated loading system of the airplane structuralstrength test is solved, the force arm adjusting control device can enable the force arm adjusting control process in the airplane structural strength test to be more intuitive and clear, and the function of automatically adjusting a force arm is realized.

Description

technical field [0001] The invention belongs to a force arm adjustment control device, in particular to a force arm adjustment control device used for an aircraft structure strength test. Background technique [0002] In the aircraft structural strength test, some tests require the state of the aircraft arm adjustment device to be controlled. The specific requirement is to control the arm adjustment device in different states according to different test load spectra. For example, in some working conditions, it is required The control arms are respectively the states of large force arm (100mm), medium force arm (80mm), medium force arm (70mm), and small force arm (60mm). [0003] Since the current testing machine only has the communication mechanism of the arm adjuster and no corresponding control equipment, similar tests cannot be carried out smoothly, and other current arm adjustment control devices cannot be used in conjunction with the coordinated loading system of the ai...
