Problems solved by technology

[0003] Chinese Patent 200920278124.0, Invention Name: "Steering gear tester" The test content proposed is relatively small, and the parameter input selectivity is not enough, and the continuous test is not smart enough. The data display can only display a single value, and there is no display and storage of process data. Conducive to future data analysis and use
In addition, this tester cannot provide a simulated load, and external equipment is required to simulate the resistance encountered by the steering gear when it is actually working, which is incomplete for the overall performance test of the steering gear

Embodiment 1

[0069] Embodiment 1 Steering gear self-inspection steps

[0070] Fix the steering gear cabin under test on the simulated load platform, connect the steering gear shaft to the rotating shaft, and connect the steering gear to the steering gear controller through cables;

[0071] The object to be tested is the steering gear cabin section on the missile, and each steering gear cabin section has four steering gears, so four steering gears can be measured at most under three test situations in the present invention, and the test data of the four steering gears are saved. But the final judgment result only gives the servo result on the selected test channel.

[0072] The test method of steering gear tester comprises the steps:

[0073] 1) Fix the steering gear cabin under test on the simulated load platform, connect the steering gear shaft to the rotating shaft, and connect the steering gear to the steering gear controller through a cable; connect the shaft transition piece between ...

Embodiment 2

[0076] Embodiment 2 square wave test steps

[0077] 1) Fix the steering gear cabin under test on the simulated load platform, connect the steering gear shaft to the rotating shaft, and connect the steering gear to the steering gear controller through a cable; connect the shaft transition piece between the photoelectric encoder and the rotating shaft of the torque sensor Take it off, turn on the main power switch, and turn on the three rocker switches on the regulated power supply, corresponding to the power supply V1, V2 and V3 respectively;

[0078] 2) Open the servo test software in the industrial control computer, its initial interface is as follows figure 2 As shown, connect the power supply V1 and V2, turn the selection knob on the steering gear controller to the steering gear test state, press the power output button on the steering gear controller, and click the "power on the steering gear" button on the software interface. Make the steering gear enter the working sta...

Abstract

The invention relates to a steering engine tester and a testing method thereof, which belong to the technical field of guided bombs. The tester comprises a control cabinet and a simulation load table, wherein the control cabinet comprises a steering engine controller, a regulated power supply, an industrial control computer, a display, a keyboard and a main power supply switch; the simulation load table comprises a photoelectric encoder, a torque sensor and a magnetic powder brake; a steering engine shaft of a steering engine to be tested is mechanically connected with a rotating shaft of the photoelectric encoder through a shaft coupling; the steering engine to be tested is in digital signal communication with the steering engine controller through a data line; and steering engine testing software is installed in the industrial control computer. The tester provided by the invention has the advantages of more plentiful testing contents, more complete testing equipment, more intelligent testing software, prompting of operating information on a software interface, shielding of keys which are required to be operated, change of parameter input items according to selected testing items, information prompt for improper operation, and great reduction in the probability of error operation.

Description

technical field [0001] The invention relates to a steering gear tester and a testing method thereof, which can control the deflection angle of the steering gear and simultaneously measure the position accuracy under different deflection angles; can provide load torque for the steering gear test and detect the value of the load torque; and can also display The utility model relates to a multifunctional comprehensive intelligent tester for storing test data, analyzing data and providing judgment results, belonging to the technical field of guided bombs. Background technique [0002] The steering gear system is the only actuator on the guided bomb. If the steering gear system fails, it is very important to quickly locate the fault, quickly detect the performance indicators of the steering gear, and ensure the normal operation of the steering gear system. The steering gear tester is mainly used for detecting and troubleshooting the steering gear system alone or regularly testing...
